Question

Using the number line as a guide, work out the difference between the numbers given.

Answer 1

Answer:

If these are addition:

1) 7

2) 3

3) 1

4) -3

5) 0

6) -5

If they are subtraction:

1) 9

2) 9

3) -7

4) 7

5) -4

6) 3

Step-by-step explanation:

Difference is subtraction, but your examples (7 and -3 = 10) implies that these are addition problems. Next time please set them up in a mathematical form.

This is how the problems would be set up:

Addition:

1) 8+(-1)= 7

2)6+(-3)= 3

3)-3+4= 1

4)2+(-5)= -3

4)-2+(-2)= 0

6)-1+(-4)= -5

Subtraction:

1) 8-(-1)= 9

2)6-(-3)= 9

3)-3-4=- 7

4)2-(-5)= 7

4)-2-(-2)= -4

6)-1-(-4)= 3
