Question:1 Write your own example of expression and equation.
Answer:1 We can say that an expression is a random combination of numbers, variables, functions, etc. For example, 3x - 2 is an expression. While on the other hand, an equation means that two different expressions are connected to each other by an equal sign in between, For example, 3x - 2 = 5 + x is an equation.
Give five examples of an expression
Example:
Identify the terms, like terms, coefficients, and constants in the expression.
9m−5n+2+m−7
First, we can rewrite the subtractions as additions.
9m−5n+2+m−7=9m+(−5n)+2+m+(−7)
So, the terms are 9m, (−5n), m, 2, and (−7).
Like terms are terms that contain the same variables.
9m and 9m are a pair of like terms. The constant terms 2 and −7 are also like terms.
Coefficients are the numerical parts of a term that contains a variable.
So, here the coefficients are 9, (−5), and 1 . ( 1 is the coefficient of the term m .)
The constant terms are the terms with no variables, in this case, 2 and −7.
