What is the difference? –1.42 – (–3.8) a. –5.22 b. –2.38 c. 2.38 d. 5.22

–1.42 – (–3.8) = C. 2.38 
(change the subtraction, and second negative sign to a postive. Its one of the many math rules when using integers... Whenever theres a subtraction sign, and a negative number to the right of it, you chnage the signs to a positive.)
sooo:
-1.42 + (3.8) = 2.38
