Question

Evaluate 12- (16) + (-8) + (-6) - 2 - (10) + (-5)

Answer 1

Answer:

$-35$

Step-by-step explanation:

Follow PEMDAS order of operations:

• Parentheses: ( )

• Exponents: a²

• Multiplication: ×

• Division: ÷

• Addition: +

• Subtraction: -

$12- (16) + (-8) + (-6) - 2 - (10) + (-5)$

Add and subtract:

• $12-\left(16\right)=-4$

• $-4+\left(-8\right)+\left(-6\right)-2-\left(10\right)+\left(-5\right)$

Apply rule: $+\left(-a\right)\:=\:-a$

• $-4-8+\left(-6\right)-2-\left(10\right)+\left(-5\right)$

• $-4-8=-12$

• $-12+\left(-6\right)-2-\left(10\right)+\left(-5\right)$

Rule: $+\left(-a\right)\:=\:-a$

• $+\left(-6\right)=-6$

• $-12-6-2-\left(10\right)+\left(-5\right)$

• $-12-6=-18$

• $-18-2-\left(10\right)+\left(-5\right)$

• $-18-2=-20$

• $-20-\left(10\right)+\left(-5\right)$

• $-20-\left(10\right)=-30$

$-30+\left(-5\right)$

Apply rule: $+\left(-a\right)\:=\:-a$

• $+\left(-5\right)=-5$

• $-30-5$

• $-35$
