Question

Find the missing value. Hint: Use the number line to find the missing value. -9-+ blank = -3 ​

Answer 1

-9 + 6 = -3

Explanation

A negative number plus a positive number gets a higher negative number. For example, -6 + 1 = -5. Since the positive number is more than the negative number, think of it like subtraction. 6 - 1 = 5, so -6 + 1 = -5. So the answer to -9 + 6 is -3.

Answer 2

You just add +6. So in the blank write 6.
