–20 + (–2) • (–6) =
132
So remember PEMDAS = parentheses, exponents, multiplication, division, addition, subtraction. This tells you the order in which you solve an equation like this. So you would first multiply -2 and -6 which= 12 and the you would add -20 which = -8 so ta-da! Your answer is -8
3 • (–8) – 2 • (–5)?
3*(-8)-2*(-5)

Same thing for that one so multiply 3*-8=-24 then multiply 2*-5=-10 then subtract -24-(-10)=-14
Simplify. 14 – 6.2 ∙ (–3 + –7) A. –78 B. –48 C. 76 D. 78
Alright so (-3+-7)=? Multiply the number you get by 6.2 then subtract that number from 14
You should get C
