Math makes shopping smarter! Use percentages and rounding to figure out discounts, final prices, and sales tax.

Round prices for fast mental math—great for staying within your budget at the store!
These skills let you spot real bargains and avoid sneaky costs.
A $25 shirt is 20% off: $25 × 0.2 = $5 off. Pay $20.
