The question
Question: find the value of 6m when m = −2.
6m
m = −2
1 Put the numbers in
We put −2 in place of m.
6m means 6 times m.
So we write a times sign.
A negative number goes in brackets, so its minus stays with it.
= 6 × (−2)
6m = 6 × m
2 Multiply
+ × − = −
Plus times minus is minus.
6 times 2 is 12.
So we get −12.
= −12
So 6m is −12 when m = −2.
Let's look back.
First: put the numbers in.
Last: multiply.
Answer
= −12
