All of them are true

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#
