Formulae S S T : S P R E A D S H E E T S SST Types of Data (Recap) Formula A mathematical expression that performs calculations Must begin with a “=” Uses operators such as “+” and “–” Operands can be entered into same cell or drawn from other cells The formula in cell B4 adds up the values in the cells B1, B2 and B3
Formulae S S T : S P R E A D S H E E T S SST Calculations In spreadsheet, we could perform calculations
Formulae S S T : S P R E A D S H E E T S SST Calculations 1.When a formula is entered into a cell, it must begin with an “=“ sign.
Formulae S S T : S P R E A D S H E E T S SST Calculations Column F is the total of Branch 1, Branch 2 and Branch 3 of each department To calculate the total in F4, we use the formula =C4+D4+E4 We then copy the formula to other cells in the same column

Formulae S S T : S P R E A D S H E E T S SST Data Entry – copying the formula Copying If the content of one cell is needed in another, you do not have to retype the content but you can copy it If you copy a formula that references other cells, the referenced cell addresses will be changed automatically in the destination cell Commands to copy cell contents Copy and paste Fill right Fill down
Formulae S S T : S P R E A D S H E E T S SST Data Entry – copying the formula To apply the formula in B5 to the other two cells, C5 and D5, select the three cells and use the Fill Right command If the hourly rate is $15, then the monthly salary for Jan in B5 is = 15 * B4
Formulae S S T : S P R E A D S H E E T S SST Data Entry – copying the formula The referenced cell addresses in the formula are changed automatically in the destination cells (C5 and D5)
Formulae S S T : S P R E A D S H E E T S SST 4 Summary 1. A formula performs calculations. It begins with an equal sign e.g. = A1+A2+A3. 2. The main operators are +, –, * and /. They follow the order of operations: brackets( ), *, /, +, Formulae can be copied to other cells. The spreadsheet program automatically adjusts the cell addresses in the formula.
