## What does it mean to solve an equation for X?

Solve for x means find the value of x that would make the equation you see true. Think about this equation: x + 1 = 3. If you were asked to solve it, that would mean finding some value for x that gives you three when you add one to it. That’s what solving an equation is all about!

## When can you solve for x in an equation?

If the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.

## What are the 3 rules of algebra?

There are many laws which govern the order in which you perform operations in arithmetic and in algebra. The three most widely discussed are the Commutative, Associative, and Distributive Laws. Over the years, people have found that when we add or multiply, the order of the numbers will not affect the outcome.

## What is the order of math equations?

It stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. PEMDAS is often expanded to the mnemonic “Please Excuse My Dear Aunt Sally”. Canada and New Zealand use BEDMAS, standing for Brackets, Exponents, Division/Multiplication, Addition/Subtraction.

## Do you multiply or add to find the area?

When you multiply the base times height you get area. For a 3-D figure you find the area of the base, then multiply it by the height, and you get the volume.

## What does difference mean in math?

more The result of subtracting one number from another. How much one number differs from another. Example: The difference between 8 and 3 is 5.

## What does the E in Pemdas mean?

exponents

## What does the G in Gemdas stand for?

GEMDAS rate. (Abbreviation) This means Grouping, Exponent, Multiplication, Division, Addition and Subtraction Order of operations 1).
