Question

What is the difference? –1.42 – (–3.8) A. –5.22 B. –2.38 C. 2.38 D. 5.22

Answer 1

–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
