The first recorded use of the plus (+) and minus (−) symbols is attributed to the German mathematician Johannes Widmann in his 1480 work "Mercantile Arithmetic." He used the symbols in the context of arithmetic operations, particularly in relation to profit and loss. While these symbols were not widely adopted immediately, they eventually became standard notation in mathematics.
Plus symbol (chinese): + Minus symbol (chinese): -
The person who invented the plus sign is the same as the minus
A "term" is each of the parts of the expression that are combined with plus or minus symbols. For example, in x2 + xy + y2, you have three terms; one before the first plus symbol; one between the two plus symbols; one after the second plus symbol.
To create a plus or minus symbol (±) using keystrokes, you can hold the "Alt" key and type "0177" on the numeric keypad in Windows. On a Mac, you can press "Option" + "Shift" + "=". Alternatively, in Microsoft Word, you can type "00B1" and then press "Alt" + "X" to convert it into the symbol.

Plus symbol (chinese): + Minus symbol (chinese): -
It indicates "plus or minus".
In Maths double sign symbols can be tabled as = + = - = - = + NB If no symbol is given in front of a number, then read it as plus(+).
a operation symbol is like minus(-) plus(+) multiply(X)and divide
The person who invented the plus sign is the same as the minus
Use a character variable. For example: plus = '+' minus = '-' You can now refer to these symbols using the variable names "plus" or "minus".
Shift-Option-Plus (+) will produce the ± symbol on a Mac.

a plus or minus sign your welcome ;D
a operation symbol is like minus(-) plus(+) multiply(X)and divide
Same mathematical signs equal plus Different mathematical signs equal minus Plus Plus = Plus (+)(+) = + Minus Minus = Plus (-)(-) = + Plus Minus = Minus (+)(-) = - Minus Plus = Minus (-)(+) = - So the direct answer to your question would be: plus minus equals minus
