8+3x(6-4)-1=13
To correctly place parentheses in the expression 8+3x6-4-1=13, we need to follow the order of operations, also known as parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right), often abbreviated as PEMDAS or BODMAS.
Let's break down the expression step by step:
Step 1: First, let's focus on the multiplication operation. Multiply 3 and 6, which equals 18:
8 + (3x6) - 4 - 1 = 8 + 18 - 4 - 1 = 8 + 18 - 5
Step 2: Next, from left to right, perform the addition operation:
8 + 18 = 26:
26 - 4 - 1 = 26 - 4 - 1 = 21
Therefore, without inserting any parentheses, the expression equals 21.
