Order of Operation Evaluate Numerical Expression

Use order of operations to evaluate this numerical expression.

When solving expressions with series of operations, which of the following is correct?

• Add and subtract from right to left

• Multiply and divide from left to right

• Add and multiply from left to right

• Subtract and divide from right to left

In the acronym for the order of operation PEMDAS, what does E stands for?
