Everyday Calculator Examples
Calculate a 20% tip on $45
45 × 0.20 = 9

Multiply the bill by 0.20 to find a 20% tip.

Split a $127 bill among 5 people
127 ÷ 5 = 25.4

Each person pays $25.40.

Total cost of 3 items at $18.50 each
18.50 × 3 = 55.50

Total cost is $55.50.

Change from $100 after $67.25 purchase
100 − 67.25 = 32.75

You get $32.75 in change.

Add up monthly expenses: $1200 + $450 + $275 + $180
1200 + 450 + 275 + 180 = 2105

Total monthly expenses are $2,105.
