Adding or subtracting the same variables together is called combining?

No, adding or subtracting the same variables together is not called combining. It is typically referred to as combining like terms or simplifying expressions.

No, adding or subtracting the same variables together is not called combining. It is known as simplifying or combining like terms. When you add or subtract variables with the same exponent or power, you combine them by adding or subtracting their coefficients. This helps to simplify the expression and make it easier to manipulate or solve.

Combining variables by adding or subtracting them together is a commonly used term in mathematics. It refers to the process of simplifying expressions by grouping like terms. Like terms are variables that have the same variable part.

For example, let's consider the expression: 2x + 3y - x + 4y

To combine the like terms, we add or subtract the coefficients of the variables. In this case, the variable "x" appears as both 2x and -x, and the variable "y" appears as 3y and 4y.

Combining like terms, we get:
2x - x + 3y + 4y

Simplifying further, we can add or subtract the coefficients:
(2 - 1)x + (3 + 4)y

Finally, combining the like terms gives us the simplified expression:
x + 7y

Thus, in this example, combining the variables x and y involves adding or subtracting the coefficients attached to them.
