Use the order of operations to evaluate the expression. 8+2(3+4)÷2

8+2(3+4)÷2 = 10

Step-by-step explanation:

The order of operation is a set of rules that guides how mathematical operations are done, to make for a universal solution.

Let us apply the rules while solving the problem 8+2(3+4)÷2

The rule is summarized in a set of Acronym known as PEMDAS

P - Parenthesis(Bracket) = (3+4) = 7

The expression becomes: 8+2(7)÷4

E - Exponents: this refers to powers, but is absent in this expression

M - multiplication: 8 + (2 × 7) ÷ 4 = 8 + 14 ÷ 7

D - Division: 8 + (14÷7) = 8 + 2

A - Addition = 8 + 2 = 10

S = subtraction. (absent in this expression)

∴ 8+2(3+4)÷2 = 10

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.
