Here I am posting simple Math Brain Riddles for Kids and Teens. These are the brain teasers I keep on preparing for my 9 years old daughter. These Math Riddles are for fun and most of these brain riddles used Mathematically operations e.g. Addition, Subtraction, Multiplication and Division. I have kept these riddles easy so that kids and teens enjoy solving these math riddles.  These Math Riddles are part of Fun Brain Teasers and Riddles.
1. IF
1x1x1 =5
2x2x2 = 10
3x3x3 = 15
4x4x4 = 20
then
6x6x6 = ?
Many people should be able to immediately answer this brain teaser.
2.  If
31 + 22 = 422
22 + 11  = 411
33 + 33 = 633
Then
44 + 55 = ?

3. IF
2 + 2 = 44
3 + 3 = 96
4 + 4 = 168
5 + 5 = 2510
Then

Another simple brain riddle which took little time for me to get it cracked.
4.  IF
3+4 = 28
2+3 = 20
5+1 = 24
3+6 = 36
THEN

3+9 = 72
THEN
7+2 =?
These brain riddles are all about Mathematical equations. Here is another simple one
7. IF
35 + 7 = 5
42 + 6 = 7
21 + 3 = 7
THEN
12 + 4 = ?
This one will require some out of box thinking. I can assure you that this one is again an easy brain riddle.

43 x 14 = 12
71 x 34 = 15
THEN
23 x 56 = ?

Lets do something different in this brain riddle then the previous Math brain riddles.
10. IF
1 + 4 = 45
4 + 2 = 86
5 + 6 = 3011
7 + 8 = 5615
Then
2 + 8 = ?
This is a simple and easy brain teaser for kids.
11. IF
3423 = 75
1234 = 37
4562 = 98
Then
1345 =?
Let us extend the idea of previous brain teaser with this math brain riddle.
12.  IF
225 x 341 = 116
345 x 751 = 196
443 x 552 = 185
Then
782 x 234 = ?
Let us change the track of this fun brain teaser
13. IF
2 9 12 = 1
1 5 10  = 4
4 6 19 = 9
Then
5 7 24 = ?
Let's give your brain some rest with this easy brain teaser question
14. IF
6+6+6+6 = 12
6+6 = 6
Then
6+6+6+6+6 =?

This is a cool brain teaser in which one has to find the missing number in the series.
15.  Which will be the missing number in this series?
5, 10, 17 , ?, 37, 50

16.  IF
1 + 2 + 3 = 343
2 + 3 + 6 = 666
3 + 4 + 5 = 985
Then
2 + 2 + 3= ?
