What is an equation?
A math statement showing two expressions are equal, connected by an equal sign (=).
What is an expression?
A math phrase without an equal sign.
Example of an equation?
8 + 3 = 11.
Example of an expression?
8 + 3.
,How do you solve for an unknown in an equation?
Apply the same operation to both sides until the unknown is isolated.
What is a variable?
A symbol (like x) that represents an unknown value.
What is a constant?
A fixed value that does not change.
What is a coefficient?
A number multiplied by a variable (in 5x, 5 is the coefficient).
How do you multiply fractions?
Multiply numerators together and denominators together.
How do you divide fractions?
Multiply by the reciprocal of the divisor.
How do you add/subtract fractions?
, Rewrite with a common denominator, then add/subtract numerators.
What is a reciprocal?
The flipped version of a fraction (e.g., 3/4 → 4/3).
What does percent mean?
Per hundred.
How do you convert a decimal to a percent?
Multiply by 100. (0.25 → 25%).
How do you convert a percent to a decimal?
Divide by 100. (75% → 0.75).
How do you find 10% of a number quickly?
Move the decimal one place to the left.
Example: What is 25% of 200?
200 × 0.25 = 50.
