Question

-30:(-3)-5-2*(-8)= -24-63:(-15+6)*(-8)= (8*7-96):(-6-4)=

Answer 1

10-5+16=21
-24-63:(-9)*(-8)= -24+7*(-8)= -24-56= -80
(56-96):(-10)= -40:(-10)=4

Answer 2

Let's break down each of the equations step by step:

1. -30:(-3)-5-2*(-8) First, we'll perform the multiplication inside the parentheses: -30:(-3)-5-2*(-8) = -30:(-3)-5-(-16) = -30:(-3)-5+16 Now, let's evaluate the division: -30:(-3)-5+16 = 10-5+16 = 21 Therefore, -30:(-3)-5-2*(-8) = 21.

2. -24-63:(-15+6)(-8) We'll start by evaluating the addition inside the parentheses: -24-63:(-15+6)(-8) = -24-63:(-9)(-8) Next, let's evaluate the multiplication inside the parentheses: -24-63:(-9)(-8) = -24-63:9*(-8) = -24-7*(-8) = -24+56 Finally, we'll perform the subtraction: -24+56 = 32 Therefore, -24-63:(-15+6)*(-8) = 32.

3. (87-96):(-6-4) First, we'll perform the multiplication: (87-96):(-6-4) = (56-96):(-6-4) Next, let's evaluate the subtraction inside the parentheses: (56-96):(-6-4) = (56-96):(-10) = -40:(-10) Finally, we'll perform the division: -40:(-10) = 4 Therefore, (8*7-96):(-6-4) = 4.

To summarize: -30:(-3)-5-2*(-8) = 21 -24-63:(-15+6)(-8) = 32 (87-96):(-6-4) = 4
