Because you're adding a negative number to a positive number, which is the same as subtracting the numbers. For example, -3+8 is the same as 8-3. All I did was just put the positive 8 at the front. Another clear way to see it is the use of a number line, negative means moving to the left, and positive means moving right on the number line. I'll make another video in the summer on the topic.

Loving the video
Thanks for watching our videos
Make a video of how to become a topper in maths ❤😊

This class is awsome but i didnt understand the first part because i never knew the word DEFERENCE is a mathematical term which means SUBTRACT
Much appreciated.
For the -3+8=5 why did you minus instead of add ?
