BEDMAS

Division and Multiplication

For example: 3x2+6/3 will always equal 8. It doesn't matter if you do division first: 3x2+6/3 =3x2+2 =6+2 =8 Or if you do multiplication first: 3x2+6/3 =6+6/3 =6+2 =8

The next steps are Multiplication and Division. Until 6th or 7th grade you were probably taught to Division and then Multiplication because in BEDMAS, the D comes before the M. In reality, it doesn't actually matter which one you do first. As long as you solve the multiplication and division from left to right, it doesn't change your answer.

Addition and Subtraction

For example: 7+9-5= 11

Lastly, you have to do the Addition and the Subtraction. Just like Multiplication and Division, it doesn't matter what you do then in. as long as you solve from left to right.

Exponents and Square Roots

Here's an example: 3^2+4=13

Next comes Exponents and Square Roots. In lower grades, we learn that the E in BEDMAS stands for Exponents. In 8th grade, the E stands for Exponents AND Square Roots. Since in 8th grade we have to solve equations with both exponents and square roots, it's important to know that they should be done together.

Brackets

If you're solving an equation with square roots, and there is an equation within the square root sign, you have to treat it like a bracket. For example: Square Root of 3+2 would actually be the Square Root of 5, because you're solving 3+2 before solving the square root.

For example, in the equation: 2x(2+4) you have to solve the equation inside the brackets before doing the multiplication.

The first letter in BEDMAS is B, which stands for Brackets. While solving an equation, you must ALWAYS solve what is within the Brackets first.
