The question
Question: work out 0.6 × 0.5 + 1.25.
0.6 × 0.5 + 1.25
1 Times and divide
Times comes before plus.
Order: ( ) → x² √ → × ÷ → + −
6 × 5 = 30
1 + 1 = 2 digits after the point → 0.30
Forget the points: 6 times 5 is 30.
Together, the numbers have 1 + 1 = 2 digits after the point.
So the answer has 2 too: 0.30, which is 0.3.
= 0.3 + 1.25
2 Plus and minus
Line up the decimal points.
We fill the gap with a 0.
A 0 at the end does not change the number.
0.3 plus 1.25 is 1.55.
= 1.55
So the answer is 1.55.
Let's look back.
First: times and divide.
Last: plus and minus.
Answer
= 1.55
