help me solve this

Hello Andrew,

It would be my pleasure to help you solve this problem.

You will want to refere to what is known as the

*"Order of operations"*. This "cheat sheet" will tell you which parts of the math problem to calculate first and which calculations to do last. There is a great mnemonic out there to help you remember the order of operations:1st:

**P**lease =**P**arentheses2nd:

**E**xcuse =**E**xponents3rd:

**M**y =**M**ultiplication4th:

**D**ear =**D**ivision5th:

**A**unt =**A**ddition6th:

**S**ally =**S**ubtractionI will now walk you through the problem you have posted using the mnemonic for the order of operations:

5(3)+2(18)-18/3= ?

**P**lease =

**Parentheses**

5

**(**3**)**= 5 X 3 = 152

**(**18**)**= 2 X 18 = 36Updated problem:
15 + 36 - 18/3 = ?

**E**xcuse =

**Exponents**

None

**M**y =

**Multiplication**

None

**D**ear =

**D**

**ivision**

18

**/**3 = 18 รท 3 = 6Updated problem: 15 + 36 -
6 = ?

**Aunt**=

**Addition**

15 + 36 = 51

Updated problem:
51 - 6 = ?

**S**ally =

**Subtraction**

51 - 6 = 45

As you can see, following the

*order of operations*leads you to your answer, 45. If you have any more questions as to how I arrived at 45, feel free to send me a private message. Good luck in your scholastic endeavors and have a great day!--Raphael B.
