• ﻿
• How to add,subtract,multiply, and divide multi-digit decimals.﻿
• Today, we are going to be learning ns.2.3.
• ﻿To add and subtract you first have to line up the decimals.Then, you add and subtract like normal. You DO NOT move the decimals. You just put them straight down in the same place they are at.
• That sounds easy enough.﻿
• For example,you have \$30.98﻿ and your mother gives you \$29.08 how much will you have? You have \$30.78 and your mom borrows \$20.08 how much will you have left?
• 30.98+29.08= 60.06 30.78 - 20.08 = 10.70
• You will have \$60.06. for number one and \$10.70 for number two.
• 30.98+29.08= 60.06 30.78 - 20.08 = 10.70
• 30.98+29.08= 60.06 30.78 - 20.08 = 10.70
• For example,you have \$30.98﻿ and your mother gives you \$29.08 how much will you have? Then, you have \$30.78 and your mom borrows \$20.08 how much will you have left?
• Exactly!﻿ Everybody got it right.
