Task to stretch your brains and make twos nine
Arrange signs of arithmetic actions and, if necessary, brackets, so that true equalitys are obtained.
These tasks will allow schoolchildren to playfully repeat the multiplication table, and adults to stretch their brains a little, while developing their creative and combinatorial abilities.
How to get 6, 15, 8 and 294 out of four sevens? Let's start with simpler examples. And to cope with them will help you products that increase the efficiency and productivity of our brain. Fill the gaps with arithmetic action signs (+;-;*;/) and brackets if necessary to make the expressions below correct.
7 7 7 7 7 = 6
7 7 7 7 7 = 15
7 7 7 7 = 8
7 7 7 7 7 = 294
How to get 7, 9, 8 and 10 out of four eights? 8 8 8 8 8 = 7
8 8 8 8 8 = 9
8 8 8 8 8 = 8
8 8 8 8 8 = 10
What signs to put between the numbers 2, 15, 7, 5 and 2 to get 100? 2 15 7 5 2 = 100
Try to find more than one solution.
How do you describe the number 9 with numbers? In a variety of ways, represent the nine with sequential digits starting with one, as well as the "+" and "-" signs between them. Dividing and multiplying signs should not be used.
1 2 3 4 5 = 9
1 2 3 4 5 6 7 8 9 = 9
How do twos make a nine? Arithmetic signs (+;-;/;*) must be placed between the numbers to make the expression true. Brackets may be used if necessary.
Without the help of Google, this puzzle is not so easy to solve. It’s time to use all of your creativity.

How to get 6, 15, 8 and 294 out of four sevens? (7 * 7 - 7): 7 = 6
7:7 + 7 + 7 = 15
(7 * 7 + 7): 7 = 8
(7 * 7 - 7) * 7 = 294
How to get 7, 9, 8 and 10 out of four eights? (8 * 8 - 8): 8 = 7
(8 * 8 + 8): 8 = 9
(8 - 8) * 8 + 8 = 8
(8 + 8): 8 + 8 = 10
What signs to put between the numbers 2, 15, 7, 5 and 2 to get 100? 2 + 15 * 7 - 5 - 2 = 100
2 * 15 + 7 * 5 * 2 = 100
How do you describe the number 9 with numbers? 1 + 2 - 3 + 4 + 5 = 9
1 + 2 + 3 - 4 + 5 - 6 + 7 - 8 + 9 = 9
How do twos make a nine? The condition does not explicitly state whether the numbers can be combined. Let’s assume that everything that is not forbidden is allowed. Then we get: 22/2 - 2 = 9.
And another witty decision, balancing on the brink of foul. If you use the "/" sign as a strikeout, we get: 2 + 2 + 2 + 2 ние 9.
