What is the difference between a numerical expression and a algebraic expression?
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.
2 divided by what gives you 52?
what divided by 2= 162
What are the example of the numerical coefficient?
In mathematics, a numerical coefficient is a constant factor in a term of an algebraic expression. For example, in the term 5x, the numerical coefficient is 5. In the expression 2y^2, the numerical coefficient is 2. Numerical coefficients can be positive, negative, integers, fractions, or even irrational numbers.
What is the difference between evaluation and simplification of an expression?
Evaluation is the process of finding the numerical value of an expression. For instance, suppose you wanted to know what x^3 was when x = 2. You would plug in 2 for x and get 2^3. This process is evaluation.Simplifying an expression on the other hand doesn't necessarily involve finding any particular value. For instance, suppose you started with the expression (x^3)/(x^2) then recognized that the numerator and denominator share a common factor of x^2 and so rewrote the expression as x. This is simplification because you've put the expression into an equivalent form that may be easier or more useful to deal with, but you have not found a specific value.You can also simplify numerical values -- for instance, 12/20 can be rewritten as 3/5. Often it's necessary to simplify a numerical expression after evaluating an algebraic one.
What is it called when you find the numerical value of an expression?
You cannot find the answer to an expression!!! An expression needs to be EQUATED' to a value, for another value to be found. 2x^(2) + 5x + 12 is an EXPRESSION. Impossible to find an value for 'x'. However, 2x^(2) + 5x + 12 = 0 is an EQUATION and a result can be calculated.
