− 7 − ( − 6 ) Explain how you could use a number line to find the difference. What is the difference?
subtract -7 and -6 on the number line and the difference is -1
I am say if I take always 4-7 That’s ways be a 28
Right!
To use a number line to find the difference between two numbers, you can visualize the numbers on the number line and then measure the distance between them.
In the given expression, -7 - (-6), you can represent -7 and -6 on a number line. Start by placing a point or mark to represent -7. Then, move to the left (since it is a negative value) by 6 units to arrive at -6.
Now, measure the distance between these two points on the number line. The difference between -7 and -6 is just 1 unit. Therefore, the difference in the given expression is 1.
So, using a number line, you can determine that the difference between -7 and -6 is 1.
