Question

8-4 5-30 _____ 3+4 7+5

Answer 1

8-4= 4

5-30= 25

3+4= 7

7+5= 12

Answer 2

To find the missing value in the equation 8-4+5-30+_____+3+4+7+5+, we can simplify the given expression by performing the addition and subtraction operations from left to right.

Starting with 8-4, we get 4. Then adding 5, we have 4+5 = 9. Subtracting 30 from 9, we get -21. Continuing with -21+_____, we need to determine the missing value.

To find the missing value, let's add the remaining numbers in the expression: 3+4+7+5. Their sum is 19.

Therefore, to complete the expression 8-4+5-30+_____+3+4+7+5+, the missing value should be 19. The complete expression becomes:

8 - 4 + 5 - 30 + 19 + 3 + 4 + 7 + 5 = -3
