Alot of people even in the university get confused when asked to solve basic maths problems like -7-7=?
They end up guessing and confusing themselves more.
Just last week when I went for a football training exercise, I saw some kids there and asked them the class they were and the school they attend.
The kids told me their class and the school they attend which was a very expensive school and when I started asking them basic mathematical questions, they couldn't answer any.
To solve-7-8=?
What you should note is that minus minus is equal to plus, so that means you will plus 7 and 8 which will give you 15.
The next step is to look for the biggest number and attach the sign that comes before it to the 15.
The biggest number is 8 and the sign that comes before it is minus.
So your answer is -15.
I hope with this my little explanation, you should be able to solve other questions involving negative and positive signs.
Thank you.
