30 -5 =x
A - B = A + (-B) A - B = A + (-B) A - B = A + (-B) A - B = A + (-B)
800 + 90 + 4 - 1 = 893
78 + yz = yz + 78
To write an expression with three terms, you need to include three different parts separated by either addition or subtraction symbols. For example, an expression with three terms could be "2x + 3y - 5z". Each part of the expression (2x, 3y, and -5z) is considered a separate term. It's important to ensure that each term is distinct and clearly separated within the expression.

If you have x+-y=z, than you can turrn it into subtraction: x-y=z. x+-y=x-y

In a numerical expression, the order of operations is indicated using parentheses to group terms, which shows what should be calculated first. According to the standard order of operations (often remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)), calculations inside parentheses are performed before any other operations. Additionally, using exponents clearly indicates that those calculations should be done prior to multiplication, division, addition, or subtraction.
