If you have x+-y=z, than you can turrn it into subtraction: x-y=z.
x+-y=x-y
800 + 90 + 4 - 1 = 893

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.
You can write the expression for 279 minus 125 in numeral form as ( 279 - 125 ). In algebraic terms, you can represent it as ( x - y ), where ( x = 279 ) and ( y = 125 ). Both forms convey the same mathematical operation of subtraction.

3-3=0
30 -5 =x
800 + 90 + 4 - 1 = 893
A - B = A + (-B) A - B = A + (-B) A - B = A + (-B) A - B = A + (-B)

You can ask it like this I have 4 apples and Mary gave me 10 more ,but my little brother ate 5. So you are using addtion and subtraction.
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.
