The question
Question: find the value of 4p + 5 when p = 0.
4p + 5
p = 0
1 Put the numbers in
We put 0 in place of p.
4p means 4 times p.
So we write a times sign.
= 4 × 0 + 5
4p = 4 × p
2 Times and divide
Times comes before plus.
Order: ( ) → x² √ → × ÷ → + −
4 times 0 is 0.
= 0 + 5
3 Plus and minus
0 plus 5 is 5.
= 5
So 4p + 5 is 5 when p = 0.
Let's look back.
First: put the numbers in.
Then: times and divide.
Last: plus and minus.
Answer
= 5
