To simplify the expression 2 + 1 × 32 – 3, we need to apply the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).
Following this order, we first identify any multiplication or division in the expression. Here, we can see there is a multiplication:
- 1 × 32
We perform this multiplication first:
1 × 32 = 32
Now we can substitute this back into the expression:
2 + 32 – 3
Now, we need to move on to addition and subtraction from left to right:
- First, we add: 2 + 32 = 34
- Then, we subtract: 34 – 3 = 31
Thus, the simplified result of the expression 2 + 1 × 32 – 3 is 31.
