Let’s Practise
Adding values.
1
Open the spreadsheet called
‘Calculations.xlsx’. On the
first worksheet labelled
‘Addition’, you’re going to
create an addition formula.
2
After typing the equals sign in cell B5, type the cell reference of the
first cell you want to add (cell B3), followed by the ‘+’ sign. Then,
type the cell reference of the second cell (cell B4). Press the ‘Enter’
key when you’re done.
Fun Time!
Subtracting from values.
Go to the second worksheet labelled ‘Subtraction’. Can you type
a subtraction formula for cells B3 and B4 in cell B5?
Challenge Yourself!
Try editing the values in the addition and subtraction worksheets. Change
the cell values and see how the result changes.
