1. Simplify: 9 + (-3) +7 x2
Answers
Answer:
20
Step-by-step explanation:
Following PEMDAS, the first thing we need to do is find out what 7 * 2 equals. This equals 14 an our new equation is:
9 + (-3) + 14
Next, going left to right, we need to find out what 9 + (-3) equals.
If there is ever an equation where it asks you to add a negative number, you can get rid of the plus sign. Now, we need to solve:
9 - 3 = 6
The new equation is:
6 + 14
Lastly:
6 + 14 = 20
