LABEL, LABEL, LABEL
Sometimes you need to use more than one operation.
We turned to Page 19 and looked at problems 1, 2, 4 and 5 .. If you missed class on Friday, make sure to review those problems.
Then we looked at Example 2 on Page 21
Simon had $165 in his checking account. He wrote checks for $32, $19, and$47. How much did Simon have left in his account?
When you write checks, you will subtract them from your balance. First add all the checks that you wrote 32 + 19 + 47 = 98. So that's $98 to subtract from the beginning balance of $165.
165- 98 = 67
So Simon had $67 left in his checking account.
Then we looked at Page 22 the Class Exercises and discussed what operations had to be used for problems # 2 and # 4.
Make sure to check out those problems.
