Using a calculator can be very helpful in mathematics but it’s important to know how to use the calculator correctly, or you could still end up with the wrong answer.
Difficult, long-winded question may need more than one step if you want to get the answer right.
Example 1 :
Let’s say that the question we got is (49.2 + 7.6) – (18.75 x 2). We’ll break this down into steps.
- First, we’ll do 49.2 + 7.6 and write its answer down.
- Then, we’ll do 18.75 x 2 and write its answer down
- Finally, we can do the subtraction.
Using a calculator to convert fractions to decimals is really easy! All you need to do is divide the numerator by the denominator.
Example 2 :
If we needed to convert into a decimal, all we need to do is take 5 and divide it by 8
5 ÷ 8 = 0. 875 therefore = 0.375
Calculators are also really handy when you’re trying to find the answer to a question that might take a lot of working out.
Example 3 :
Let’s say the question we’ve been given is ‘find two numbers that add together to make 20 and multiply together to make 96’.
We know which pairs of numbers will add together to make 20 so let’s do a couple of sums to try and guess the answer.
10 x 10 = 100 – this answer is too big
15 x 5 = 75 – this answer is too small
The real answer must be in between these two
12 x 8 = 96 – we got the right answer
With a calculator, we could have done lots of sums very quickly to get the right answer.
