Use 4 fours and any operations and mathematical signs to write number sentences that equal 1 through 10. Study the strategies you used to create the number sentences using threes to see if some of the same strategies can also be used for the number sentences using fours.

See answer below.

Step-by-step explanation:

This exercise requires practice and trying to find different numbers we can create using forms. It is important to notice that in general we'll be using 4/4 = 1, when we need to add or subtract a one.

1 = 4/4 + 4 - 4 = 1 + 4 - 4 = 1

2 = 4 - (4 + 4) / 4 = 4 - 8/4 = 4 - 2 = 2

3 = (4 + 4 + 4) / 4 = 12/4 = 3

4 = 4 + 4 (4 - 4) = 4 + 4 (0) = 4 + 0 = 4

5 = ((4) (4) + 4) / 4 = (16 + 4) / 4 = 20/4 = 5

6 = (4 + 4) / 4 + 4 = 8/4 + 4 = 2 + 4 = 6

7 = 4 + 4 - 4/4 = 8 - 1 = 7

8 = (4/4) (4) + 4 = 1 (4) + 4 = 4 + 4 = 8

9 = 4 + 4 + 4/4 = 8 + 1 = 9

10 = 4 / √4 + 4 (√4) = 4/2 + 4 (2) = 2 + 8 = 10
