Cheat Sheet
- Identifying Primes vs. Composites -
Prime numbers have exactly two distinct positive divisors (1 and itself), while composites have more. For instance, 17 is prime but 18 is composite (divisible by 2, 3, 6, 9). Using the Sieve of Eratosthenes (MIT OCW) is a reliable way to list primes up to any limit.
- Order of Operations (PEMDAS) -
Remember PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction) to solve expressions correctly. For example, in 3 + 4 × (2^2), calculate the exponent 2^2=4, then 4×4=16, and finally 3+16=19. This rule is endorsed by the National Council of Teachers of Mathematics for consistent arithmetic results.
- Properties of Arithmetic Operations -
The commutative, associative, and distributive properties (per Khan Academy) simplify calculations: a+b = b+a, (a+b)+c = a+(b+c), and a(b+c) = ab + ac. For instance, 5×(2+3) = 5×2 + 5×3 = 25. Recognizing these saves time and reduces errors in complex problems.
- Mental Math & Number Decomposition -
Break numbers into friendly chunks: 47+38 becomes (40+30)+(7+8) = 70+15 = 85. For multiplication, use (a+b)(c+d) expansions like 12×15 = (10+2)(10+5) = 100+50+20+10 = 180. Such strategies are recommended by the Mathematical Association of America to boost speed.
- Divisibility Rules for Fast Checks -
Quick tests help spot composites: a number is divisible by 3 if its digits sum to a multiple of 3 (e.g., 123 → 1+2+3=6). For 11, subtract and add alternating digits (e.g., 2 - 5+4=1, not a multiple of 11). These rules, from Wolfram MathWorld, streamline factorization in pop quizzes.
