When adding dollars, try breaking apart the money into their respective units (20, 10, 5, and 1 dollar bills) and adding the like units together and then combining the totals.For example, if you are adding $45 to 1 $10, 2 $5s, and 3 $1s
Break apart $45 into 4 $10s and 1 $5
Combine the 4 $10s and the 1 $10, and then the 1 $5 and the 2 $5s
Sum up each bill type (5 $10s = $50, 3 $5s = $15, 3 $1s = $3)
