Question #f4200

Answer 1

All of them are true

Explanation:

a. `59+(-26)=59-26=33`

b. `-62-(-34)=-62+34=-28`

c. `-46xx(-5)=46xx(5)=230`

d. `380//(-4)=-95`

When multiplying or dividing a negative by a negative the answer is positive.
e.g. `(color(blue)-10)//(color(blue)-2)=5`

When multiplying or dividing a negative by a positive the answer is negative.
e.g. `5xx(color(blue)-2)=color(blue)-10`

Adding a negative is the same as subtracting the number.
e.g. `5+(-color(blue)2)=5-color(blue)2=3`

Subtracting a negative is the same as adding the number.
e.g. `5-(-color(blue)2)=5+color(blue)2=7`
