What is #[(8+10) -: 3] + 3 * (7-3)#?

Question

Riley Anderson · Accepted Answer

18

PEMDAS, parentheses first #(8+10)# and #(7-3)# #[18 ÷ 3] + 3(4)# Parenthases again # 6 + 12# then add #18#

Jeremiah Andrews · Answer

undefined To evaluate the expression [(8+10) ÷ 3] + 3 * (7-3), follow the order of operations (PEMDAS/BODMAS):

1. Perform operations inside parentheses/brackets: (8 + 10) = 18, (7 - 3) = 4.
2. Evaluate the multiplication and division: [(8 + 10) ÷ 3] = 18 ÷ 3 = 6, 3 * (7 - 3) = 3 * 4 = 12.
3. Perform addition: 6 + 12 = 18.

So, the value of the expression is 18.

Autumn Arnold · Answer

undefined To solve the expression $[(8+10) \div 3] + 3 \times (7-3)$, follow the order of operations, which is PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right):

1. Inside the parentheses, perform the operations:
$$ (8 + 10) = 18 $$
$$ (7 - 3) = 4 $$

2. Next, solve the division and multiplication operations:
$$ 18 \div 3 = 6 $$
$$ 3 \times 4 = 12 $$

3. Finally, perform the addition operation:
$$ 6 + 12 = 18 $$

So, $[(8+10) \div 3] + 3 \times (7-3) = 18$.
