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
