2.75+.003+.158=

and your thinking is...?

2.911
But I think you can't just use a calculator to solve.
Let me show you how to solve without.
Remember to line up the decimals!
2.750
.003
.158
Essentially for the decimal spot, you're just adding 750, plus 3, plus 158. You can easily calculate that in your head to be 911.
Then you just add it to the 2.
2.911
Get it?
