Question

3. 7.NS.1.2
Evaluate the following expression.
2 + (3 – 2 x 2) x 1

Answer 1

Explanation:

2 + (3 – 2 x 2) x 1

This is what I remember, but you need to check this order of arithmetic operations.

Parentheses first then exponents ( you don't have any) multiplication and division left to right and then addition and subtraction again left to right

2 + (3 – 2 x 2) x 1 so 3 – 2 x 2 equals 3 - 4 which equaltes to

2 + (-1) x 1 -1 x 1 = -1

2 + (-1) x 1 is to clearer to me than 2 + -1 x 1 maybe not

2 + -1

1 it confusing but use your calculator to practice
