How do you make a minus sign with the keyboard?

go to the character map in the start menu. (for PC)

Type 0162 on the number pad on the right side of the keyboard while holding down "Alt."

you can make a triangle, triangle means devil ? ▲ haha

Depending on what type of keyboard you have, this may not be possible. You just have to stick with *The* sign is multiplication this / is the division/divide sign which is located on the right side...
