Basics of Spreadsheets
Everyone needs to perform simple math. Businesses need to keep track of sales and profits, and individuals need to keep
track of budgets. In the old days, people not only had to write down numbers on paper, but they also had to do all their
calculations by hand (or with the aid of a calculator).
That is why people use Excel. Instead of writing numbers on paper, they can type numbers on the computer. Instead of adding
or subtracting columns or rows of numbers by hand, Excel can do it for you automatically. Basically, Excel makes it easy to
type and modify numbers and then calculate new results accurately and quickly.
