Q2) $(+5) - (-8) + (10)$ is called a math expression.

Q3) Calculate the following:
A) $3x-5=$
This expression cannot be simplified further without a specific value for $x$ .

3x-5 = \boxed{3x-5}

B) $(-9) \times 10=$

Multiply the absolute values.
$9 \times 10 = 90$
Apply the sign rule (negative $\times$ positive = negative).
$(-9) \times 10 = \boxed{-90}$
C) $(-12) \times f =$
This expression cannot be simplified further without a specific value for $f$ .
$(-12) \times f = \boxed{-12f}$

Simplify or evaluate the following mathematical expressions: A) 3x-5 B) (-9) 10 C) (-12) f. Also, what is (+5) - (-8) + (10)?

Step-by-step solution

Multiply the absolute values.

Apply the sign rule (negative $\times$ positive = negative).
