Answer:
Use estimation
Step-by-step explanation:
A) 99 + 54
estimate that 99 is 100
estimate that 54 is 55
Add 100 and 55 together
100 + 55 = 155
Remember that you added 1 to 99 and 1 to 55
So you must subtract 2 from 155
155 - 2 = 153
Your answer is 153.
B) 244 - 99
estimate that 244 is 245
estimate that 99 is 100
Add 245 and 100 together
245 + 100 = 345
Remember that you added 1 to 245 and 1 to 99
So you must subtract 2 from 345
345 - 2 = 343
Your answer is 343.
