How do you find factors?

To find factors of a number, systematically test small whole numbers (starting with 1) to see if they divide your target number evenly; if a number divides it perfectly, both the divisor and the result (quotient) are factors, and you keep going until the numbers you're testing meet in the middle, listing all pairs and the numbers themselves to get the full list. For example, for 12: 1x12, 2x6, 3x4, so factors are 1, 2, 3, 4, 6, 12.

What is the butterfly method in math?

The "butterfly method" in math is a simple, visual trick for adding, subtracting, or comparing two fractions by drawing "wings" and "antennae" to cross-multiply numerators and denominators, creating a mnemonic device that's easy for beginners but lacks conceptual depth. It works by cross-multiplying diagonally to find the numerator(s) and multiplying the denominators for the final denominator, making fractions like 3/4 + 2/5 become (3×5 + 2×4) / (4×5) = 23/20.
