Subject: [Blindmath] Using minus signs before negative numbers

Hello everyone,
What/where is the rule that explains how to write a minus sign
followed by a negative number? For example, in the expression 3 minus
negative 5. I have found specific rules/examples for when the negative
sign is superscript, but how would I write it when the negative sign
is on the line with the numeral?

Thanks for your help.

-Greg
