How do you use PEMDAS to simplify #3 times 2 - (8+1) #?

Answer 1

#3xx2-(8+1)= -3#

PEMDAS stands for Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction. Hence we solve in this order - first parentheses, then exponents, then multiplication and division and finally addition and subtraction.

Hence #3xx2-(8+1)#

= #3xx2-9#

= #6-9 = -3#

To simplify the expression (3 \times 2 - (8 + 1)) using PEMDAS:

Perform operations inside parentheses: (8 + 1 = 9).
Substitute the result into the expression: (3 \times 2 - 9).
Multiply: (3 \times 2 = 6).
Subtract: (6 - 9 = -3).

So, (3 \times 2 - (8 + 1)) simplifies to (-3) using PEMDAS.
