Evaluate the expression. 1×(4+ – 3×8)
1×(4+ – 3×8) = 1×(4 – 24)
= 1×(-20)
= -20
To evaluate the expression 1 × (4 + (-3) × 8), we need to follow the order of operations, also known as PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Step 1: Evaluate inside parentheses: 4 + (-3) × 8
Since the multiplication operation comes first, we multiply -3 by 8.
4 + (-24)
Step 2: Perform addition: 4 + (-24)
4 - 24 = -20
Step 3: Multiply: 1 × (-20)
1 × (-20) = -20
Therefore, the expression 1 × (4 + (-3) × 8) evaluates to -20.
To evaluate the expression 1 × (4 + (-3) × 8), we follow the order of operations known as PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
1. First, we simplify the expression inside the parentheses.
4 + (-3) × 8 = 4 + (-24)
2. Next, we multiply -3 and 8.
4 + (-24) = 4 - 24
3. Finally, we perform the addition:
4 - 24 = -20
Therefore, the value of the expression 1 × (4 + (-3) × 8) is -20.
