Four Operations

Addition

Simple addition questions, like 5+11, can be easily calculated ourselves or by using a calculator and typing in 5+11= giving us 16.

We may come across more complicated questions, such as:

If Sally has \text{£}12, and for her birthday she is given \text{£}230 from her mum, \text{£}162 from her dad, and \text{£}51 from her brother, how much money does she now have?

We can similarly work this out by typing the following into our calculator:

Subtraction

Similarly to addition, we can use our calculator to work out subtraction questions, for example:

If Sally has \text{£}455, and she spends \text{£}80 on shoes, \text{£}118 on jumpers, and \text{£}66 on jewellery, how much money would she have remaining?

We can work this out by typing the following into our calculator:

455-80-118-66=\text{£}191.

Multiplication

Simple multiplication questions, like 4\times5, can be easily calculated ourselves or  by using a calculator and typing in 4\times5=, giving us 20.

We may come across more complicated questions, such as:

Freddie buys 6 chocolate bars for 55\text{ p} each, how much does he spend in total?

We can similarly work this out by typing the following into our calculator:

6\times55=330\text{ p}.

Division

Similarly to multiplication, we can use our calculator to work out division questions, for example:

Freddie spends 605\text{ p} on chocolate bars. Each chocolate bar costs 55\text{ p}, how many chocolate bars does Freddie buy?

We can similarly work this out by typing the following into our calculator:

605\div55=11 chocolate bars.
