TIPS and TRICKS to PASS Module 4 Spreadsheets
REMEMBER: All formula's start with an = sign
To get your calculations right you MUST learn and follow this order in Excel and in the ECDL tests:
Excel Order of Calculation
( )
Calculations in brackets are ALWAYS done FIRST,
then
x or /
multiplications or division
and then LAST
+ or -
addition or subtraction
Look at the following examples and try them in Excel:
Add Addition + Formula
Cell B4 add (+)Cell B5 =
Formula
=B4+B5
Subtraction - Formula
Cell E5 subtract (-)Cell E6 =
Formula
=E5-E6
Multiply x Formula
Cell E7 multiply (*) Cell B10 =
Formula
=E7*B10
Divide Formula
Cell B9 divide(/) by 4 =
(Total cost of holiday for 4 people divided by 4 to give individual cost per person)
Formula
=B9/4
Combined Formula
Cell B4 subtract (-) 32 = then divide (/) answer by 1.8 =
The bracket part of the formula MUST be calculated first so that the bracket answer is used to base the second part of the formula on
i.e. 275 - 32 = 243
243 divided by 1.8 = 135
Formula
=(B4-32)/1.8
Percentage Formula
Cell B6 divided (/) by Cell B13 select % button =
The percentage is calculated by dividing the value of B6 Total Police Expense by the total of Expenses in B13 and pressing the % button
i.e. 1,400,000 divided by 9,560,000 = 15%
Formula
=B6/B13
Copying Formula
Absolute Reference
If you need to change the formula in a cell so that is dosn't become relative where it changes with all formulas as in above, you make the cell reference absolute by placing a dollar sign in the row and column reference.
This means that the formula can be copied and used elsewhere, but it will always refer to value of A1 cell.
Formula
=$A$1
In the example below, the formula contains an absolute reference to cell C3 to ensure that 10% is calculated for all staff bonus cells from C6 to C8
ie. Jim Myers Salary of £12,000 multiply 10% = £1,200
Mixed Cell Reference
In a mixed formula the Row reference is the 2nd digit ie. =B$2 means column B, row 2. The dollar infront of the Row digit indicated that the row cell is absolute only.
In the example below, we have a formula setup to enable the row numbers in Row 3 to multiply the column numbers in column B
