Basic Calculator Skills

The calculator will not make a mistake if you give it the correct instructions. Look at this example:

Example 2.2a

Add together £5.32 and 89p.

Solution:

If you key in 5.32 [+] 89 [=] you will get the answer 94.32 which is wrong, of course.

Enter the numbers in pounds or pence either 5.32 + 0.89 = 6.21 this representing £6.21 or 532 + 89 = 621 this representing 621p which you then translate into pounds.
