Mastering Decimal Multiplication and Division

Stop letting floating dots ruin your math score. When you multiply decimals,

literally just pretend the points aren't there. Multiply the numbers normally like you

always do, then count the total decimal places in the original problem. Slide the dot that

many spots to the left in your answer. Done. For division, it’s a sliding game.

Move the decimal on the outside number until it’s whole, do the exact same slide to the inside

number, and shoot the dot straight up. Even exponents are just multiplying

the decimal by itself. It’s just counting scoops, so put the calculator away.
