<h3>Be a Math Wizard (or Mind Reader?)<a name="mind" class="kids-anchor" id="mind"></a> </h3>
|
||
<p>Here is a math trick you can play on your friends to show them what a math whiz you are! Tell a friend that the two of you will pick five 5-digit numbers at random, and then will add them together -- but, amazingly, after just hearing the first number and before the others have even been selected, you'll be able to accurately predict what the TOTAL of those five numbers will be!</p>
|
||
<h3>Steps:</h3>
|
||
<ol>
|
||
<li>Have a friend write down a 5-digit number -- for example, he might write down 67,812.</li>
|
||
<li>Then on a separate piece of paper, you can immediately write down the final "answer" to this quiz (the total of all five numbers), even though four of the numbers haven't even been selected yet! For the example given, 67,812, the answer will be 267,810.</li>
|
||
<li>Announce that you have "predicted" the final answer and written it down as proof -- but don't show it yet. Just fold the piece of paper over to keep that answer hidden till the end of the "trick".</li>
|
||
<li>Then have your friend write down a second 5-digit number right beneath the first one.<br> You then quickly write down a third 5-digit number right below it (but you'll have to know what to write -- to find out, visit the instructions below!).</li>
|
||
<li>Then have your friend write a fourth 5-digit number under your number. Then you immediately write a fifth 5-digit number beneath it (again, you'd select that number according to the instructions below ).</li>
|
||
<li>Then ask your friend to add up the five 5-digit numbers that have been written down.</li>
|
||
<li>Compare that answer to the one you wrote down after the first number was selected.</li>
|
||
</ol>
|
||
<p>Amazingly, they will be identical! But how could you do that? How could you predict the total after just hearing the first number? Just follow the instructions below!</p>
|
||
<p>Instructions/Answer<a name="instructions" class="kids-anchor" id="instructions"></a> Here is the trick: (1) Take the first number and subtract 2 from it then put the number "2" in front of it. (For example, if the number was 67,812, it would be 267,810). That will be the final answer. (2) Then, when you see the second number your friend writes down you mentally subtract each digit of that number from 9, and write that answer for the third number. (For example, if your friend's second number is 11,111, then the number you would choose and write down would be 88,888. Or, if your friend's number is 56,123, then your next number would be 43,876. The key here is that each of your friend's number's digits, when added to the corresponding digit of your number, must total 9.) Then you ask your friend to write down a fourth number, and again you subtract each digit of that number from 9 (do this silently!), and write that answer down as the fifth number. For example, if the second number is 12,345, then you would write 87,654 as the third number because(12345 + 87654=99999). When the 5 numbers the two of you selected are all added together, the total will be identical to the number you originally wrote down and set aside! It works every time. Try it and see!</p>

<h3>Phone A Friend<a name="phone" class="kids-anchor" id="phone"></a> </h3>
|
||
<p>It's time to phone a friend for a little math fun ...get your calculator...this works!</p>
|
||
<p>(Note: Ignore your area code and use only your seven digit phone number)</p>
|
||
<p>1) What are the first 3 digits of your phone number? (do NOT include the area code)<br> <input name="practice1" title="practice2" aria-label="practice2" type="text" size="10"></p>
|
||
<p>2) Multiply by 80<br> <input name="practice1" title="practice2" aria-label="practice2" type="text" size="10"></p>
|
||
<p>3) Add 1<br> <input name="practice1" title="practice2" aria-label="practice2" type="text" size="10"></p>
|
||
<p>4) Multiply by 250<br> <input name="practice1" title="practice2" aria-label="practice2" type="text" size="10"></p>
|
||
<p>5) Add in the last four digits of phone number<br> <input name="practice1" title="practice2" aria-label="practice2" type="text" size="10"></p>
|
||
<p>6) Add in the last four digits of phone number again<br> <input name="practice1" title="practice2" aria-label="practice2" type="text" size="10"></p>
|
||
<p>7) Subtract 250<br> <input name="practice1" title="practice2" aria-label="practice2" type="text" size="10"></p>
|
||
<p>8) Divide by 2.<br> <input name="practice1" title="practice2" aria-label="practice2" type="text" size="10"></p>
|
||
<p>Is the result your phone number?</p>
|
||
<div class="answer-hover"><strong>Explanation</strong>
|
||
<div class="answer">
|
||
<p>This is a little algebra problem. Let X denote the first three digits of the phone number and Y the last four digits. Then let's take the calculations a step at a time.</p>
|
||
<ol>
|
||
<li>X</li>
|
||
<li>80X</li>
|
||
<li>80X +1</li>
|
||
<li>250 (80X+1) or 20,000X + 250</li>
|
||
<li>20,000X + 250 + Y</li>
|
||
<li>20,000X + 250 + 2Y</li>
|
||
<li>20,000X + 250 + 2Y -250 or 20,000X + 2Y</li>
|
||
<li>(20,000X + 2Y)/2 or 10,000X + Y</li>
|
||
</ol>
|
||
<p>Thus, no matter what your phone number is, the final number will repeat your phone number. The 10,000 multiplier is needed to move the first three digits over four decimal places).</p>

<h3>Pick-Pocket Game<a name="pick" class="kids-anchor" id="pick"></a> </h3>
|
||
<p>This will take a calculator, but it will be worth it! You can impress your friends and family by correctly guessing the amount of change they have in their pockets!</p>
|
||
<p>Ask the person to take his/her age and multiply it by 2.<br> <input name="practice1" title="practice2" aria-label="practice2" type="text" size="20"></p>
|
||
<p>Add 5.<br> <input name="practice1" title="practice2" aria-label="practice2" type="text" size="20"></p>
|
||
<p>Multiply this sum by 50.<br> <input name="practice1" title="practice2" aria-label="practice2" type="text" size="20"></p>
|
||
<p>Subtract 365.<br> <input name="practice1" title="practice2" aria-label="practice2" type="text" size="20"></p>
|
||
<p>Add the amount of loose pocket change, but do NOT count change totalling $1 or over (i.e., must be less than $1)<br> <input name="practice1" title="practice2" aria-label="practice2" type="text" size="20"></p>
|
||
<p>Add 115 -- final outcome:<br> <input name="practice1" title="practice2" aria-label="practice2" type="text" size="20"></p>
|
||
<p>Notice that the first two digits will be the person's age,<br> and the last two digits are the amount of the person's pocket change.</p>
