Understanding mathematical language and symbols is an integral part of learning many

mathematical concepts. No one can think mathematically or express themselves in mathematical

terms unless they have first learnt the correct meaning of the words to use.

Here are 3 sets of mathematics trivia questions. See how much you know about mathematical

terms. To check your answers please scroll below......

Have fun!!!

Nine times any number equals nine

You may already know that nine times any number equals nine. There are some amazing puzzlesor tricks that have been developed using this mathematical phenomenon.

First, let me explain what I mean by nine times any numberequals nine. Look at the

multiplication table under the 9. You will see that 9x1=9; 9x2=18...the 1 and 8, when addedtogether, equals 9. Every multiple of nine, when added together equals nine: 27, 2+7; 36, 3+6,

etc.

With that in mind, try the following trick on a friend (you will be able to tell them which number

they have circled without ever having seen the numbers):

1. Have them write any three to five digit numberwithout letting you see the number. Makesure they do not use zero or duplicate numbers.

2. Then, have them randomly rearrange the same numbers to form a new number.3. Now they have two different numbers with the same amount of digits.4. Have them subtract the smaller number from the larger number.5. Ask if their answer has any zeros.6. Tell them to circle one digit of the answer without letting you know any of the numbers.

(Make sure they do not circle a zero)


5/6

7. Ask what numbers are left over. The circled number being a secret.8. Add the total of the digits. The number they circled will be the difference between the

total of the digits and the next higher multiple of nine.

Example:

259 (secret three digit number)

952 (randomly rearranged three digit number using the same three numbers)

952-259=693

They circle the 9. They tell you that they have a 6 and a 3 left. 6+3=9, the next multiple of nine is

18. So 18-9=9...this is how you know they circled a 9. :)

Easy enough? Let's do one more:

45689 (secret number)

98654 (the same digits randomly rearranged)

98654-45689=52965

They circle a 5. They tell you that they have 5,2,9,6 left. 5+2+9+6=22. The next higher multipleof nine is 27. So, 27-22=5...you know they circled a 5.

TIPS:

If they make an error in their math, your answer will be wrong--so make sure they doublecheck their math before telling you the numbers that are left over.

You can do this with any number that is two digit or higher. Two digit numbers very quickly reveal how you know what number is circled, while

larger numbers make it more likely that there will be an error in the math making youranswer wrong.

It is perfectly fine if they use a calculator.******************************************************************************

Here's another good one:

1. Have someone pick a number between 1 and 9 without telling you what number theychose.

2. Tell them to multiply their chosen number by 9.3. Confirm that the answer is a two-digit number (but don't let them reveal the actual

number to you).

4. Tell them to add the two digits together.


6/6

5. Now have them subtract 5 from that number.6. Explain that the number needs to be assigned a letter to represent it, and that 1=A, 2=B,

3=C, 4=D, 5=E, etc.

7. Now have them think of a COUNTRY that begins with the letter represented by theirnumber.

8.

Next, have them think of an ANIMAL that begins with the last letterof the COUNTRY.9. Then, have them choose a COLORthat begins with the last letterof the ANIMAL.10.Give them a moment to look at what they have written, then tell them "there are no

orange kangaroos in Denmark!"

11.99% of the people will have written those three things down! It will blow away yourfriends when you try this. :)

Here's how it works: When they choose a number between one and nine, then multiply it by 9,the answer of the two digits added together will be 9 (every number multiplied by nine is nine,

right?). Then you have them subtract 5 from that answer, leaving a 4. So, the representative letter

will always be D. 99% of people will list Denmark as the country beginning with D, Kangaroo as

the animal beginning with K, and Orange as the color beginning with O. Try this and let meknow how it works for you. This is a great one to do over the phone--where the other party

knows it is impossible for you to have seen what they wrote down. :)
