MATH QUIZ WORD PROBLEMS TO EXPRESSIONS Learn to turn real-life situations into algebraic expressions! What Are Word Problem Expressions? Many real-life situations involve fixed amounts (constants) and changing amounts (variables). Your job is to identify which is which, then write the correct algebraic expression. Key Words to Remember "Per" and "each" mean multiply the rate by the variable. "Plus" and "and" (for cost) mean add the parts together. "Times as many" means multiply the quantity by that number. For geometry: Perimeter = 2(length + width) , Area = length × width Common Mistakes Don't multiply the fixed fee by the variable! A flat charge like "₱40" stays as 40 , not 40x. Only the "per unit" part gets multiplied. Tip: Always ask yourself — "What stays the same?" (constant) and "What changes?" (variable × rate). Then combine them! Tr...
MATH QUIZ MULTIPLYING & DIVIDING MONOMIALS Master the three rules: Product, Quotient, and Negative Exponent! Product Rule (Multiplication) Multiply the coefficients , then ADD the exponents of the same variables. x³ · x⁴ = x 3 + 4 = x⁷ (2a²)(3a) = 6a 2 + 1 = 6a³ Quotient Rule (Division) Divide the coefficients , then SUBTRACT the exponents of the same variables. x⁵ x² = x 5 − 2 = x³ 12m⁴ 4m = 3m 4 − 1 = 3m³ Negative Exponent Rule A negative exponent means the term moves to the denominator and becomes positive. x⁻² = 1 x² 2x⁻³ = 2 x³ Quick Examples Multiply: (4x²)(3x³) → 12x 2 + 3 = 12x⁵ Divide: 20a⁵ 5a² → 4a 5 − 2 = 4a³ Negative: x⁴ x⁷ → x 4 − 7 = x⁻³ = 1 x³ Power: (2x³)² → 2 2 x 3 × 2 = 4x⁶ Remember: Same base? Multiply = ADD , Divide = SUBTRACT , Power = MULTIPLY ! Quiz Time! Read carefully and pick the best answer. You got this! Answer all questions first before submitting! SUBMIT ...
