10 practice questions!! need help!
what is the value of the expression?
12+6*2/18-3*5

Answer 1

Order of operations:

1. Do all multiplications and divisions in order from left to right.

2. Do all additions and subtractions in order from left to right.

Answer 2

Does your problem look like this?

\(\rm \Large \frac{12~+~6\times 2}{18~-~3\times 5}\)

Answer 3

yes it does. i didnt know how to make it look like that

Answer 4

Ah okay

So make sure you follow the Order of Operations

P - Parenthesis
E - Exponents
M & D - Multiplication & Division
A & S - Adding and Subtracting

As we see there is no parenthesis nor exponents, so we move on the Multiplying and Dividing

\(\rm \Large \frac{12~+~\color{red}{6\times 2}}{18~-~\color{red}{3\times 5}}\)

So what is \(\rm \color{red}{6\times 2}\) and \(\rm \color{red}{3\times 5}\)

Answer 5

6*2= 12 and 3*5=15

Answer 6

And like @skullpatrol said, make sure you do the multiplication and subtraction left from right, and same with addition and subtraction.

Answer 7

ok so it would be 12+12 divided by 18-15

Answer 8

Good! Now we plug in \(12\) where \(6\times 2\) was, and \(15\) where \(3 \times 5\) was in the equation


\(\rm \Large \frac{12~+~\color{red}{6\times 2}}{18~-~\color{red}{3\times 5}}\)

\(\rm \Large \frac{12~+~\color{red}{12}}{18~-~\color{red}{15}}\)

Now we must do the addition and subtraction.

What is \(12~+~12\) and \(18~-~15\)?

Answer 9

24 divided by 3 which equals 7
