it has to have an x number in it.
Numerical equations have only numbers and symbols, while algebraic equations have variables also.
abs(9 - 3)/2
a numerical expression is just an expression without any equal or unequal signs, e.g. (a+2b)c or 5x-6y an equation shows two expressions with an equal sign, e.g. (a+2b)c = 53 or 5x-6y = 3k2-7k+21
You evaluate the expression !! :)
Numerical Expression
A variable expression includes variables.
The variable.
algebric uses variables and numerical uses numbers
The variable.
Numerical equations have only numbers and symbols, while algebraic equations have variables also.
Numerical expressions solely include numbers, while algebraic expressions may contain a variable like x. An example of a numerical expression is 1+2 and an example of an algebraic expression is 2x+3y=0.
Numerical Expression: 1.) 20+2-8 ( Or any other number with two symbols on math ) Algebraic Expression: 2.) h x 2 ( Or any other number using only one symbol an a letter ) The difference between a numerical and algebraic expressions is that numerical expressions use only numbers, but algebraic expressions use letters as variables to represent numbers.
abs(9 - 3)/2
Numerical expression: 59-34*6 Algebraic expression: 5x-3x+2 A numerical expression is limited to only numbers and can always be simplified to one number. An algebraic expressuion uses terms, more specifically a variable like x, and a constant like 2.
2(25-15)=2 x 10=20
A numerical expression uses numbers and operations. It also has an equal sign. An algebraic expression uses variables and operations. Unlike a numerical expression it does not have an equal sign.
What is the difference between evaluating an expression?
