Basic Rules for Adding Money

1. Line up decimal points when writing amounts
2. Add bills first, then coins
3. Convert coins to dollar amounts for easier calculation
4. Check your work by counting again

Adding Whole Dollar Amounts

Example 1: Simple Bill Addition

Problem: You have 10and10and5. How much do you have in total?

Solution:

1. Write the amounts: 10.00+10.00+5.00
2. Add the numbers: 10 + 5 = 15
3. Final amount: $15.00

Answer: You have $15.00 total.

Example 2: Multiple Bill Addition

Problem: You have 20,20,15, and $3. How much is that altogether?

Solution:

1. Write the amounts: 20.00+20.00+15.00 + $3.00
2. Add step-by-step:
   • First: 20 + 15 = 35
   • Then: 35 + 3 = 38
3. Final amount: $38.00

Answer: You have $38.00 total.

Adding Bills and Coins Together

Example 3: Mixed Bills and Coins

Problem: You have 2 quarters (0.50),3dimes(0.50),3dimes(0.30), and a $5 bill. How much money do you have?

Solution:

1. Calculate coins first:
   • 2 quarters = 25¢ × 2 = 50¢ ($0.50)
   • 3 dimes = 10¢ × 3 = 30¢ ($0.30)
   • Total coins: 0.50+0.50+0.30 = $0.80
2. Add the bill:
   • 5.00(bill)+5.00(bill)+0.80 (coins) = $5.80

Answer: You have $5.80 total.

More Challenging Examples

Example 4: Larger Amounts with Coins

Problem: You have 25.50,25.50,10.75, and $5.25. What’s the total?

Solution:

1. Add dollars first: 25 + 10 + 5 = $40
2. Add cents separately: 50¢ + 75¢ + 25¢ = 150¢ ($1.50)
3. Combine: 40+40+1.50 = $41.50

Answer: $41.50 total.

Example 5: Counting Up to $100

Problem: You have 3 × 20bills,5×20bills,5×5 bills, and 4 quarters. How much is this?

Solution:

1. Calculate bills:
   • 3 × 20=20=60
   • 5 × 5=5=25
   • Total bills: 60+60+25 = $85
2. Calculate coins:
   • 4 quarters = $1.00
3. Combine: 85+85+1 = $86

Answer: $86.00 total.
