• Why do we estimate instead of doing the problem
• Doing an estimate doesn't mean that you won't get the same answer as it really is. this can be the case though. if you pay the cashier \$1.02 he will have to give you 2c back. and this would waste time. so you can just give him that.
• What must you do if your estimates are incorrect or not even close to your actual answer?
• Think about the situation again with a clear mind and you will be able to find your mistake and correct it .

Good Luck !!
• why does we's have to estimates? CANT WE JUST BE SMART AND SOLVE IT?
• it is more as an approximation as it can be not drawn to scale
• Is the total amount of humans in the Earth is a estimate or a real number ?
• Estimate because it is always increasing and decreasing.
• What does Estimate mean?
• When you estimate, you roughly find out a value. It's not an exact answer, but instead a number close to the actual value or a range that has the value in it. You can estimate when you're not sure of the actual answer, like Sal did in the video.
