What do you call the order used to do arithmethic in nummerical expression?
It is the order of arithmetical operations and is known as BODMAS or BIDMAS meaning brackets, indices, division, multiplication, addition and subtraction
What is the algebraic expression for the product of 5 and a number?
If you call your number x, the expression would be 5x.
How do you factor 5x2 - 4x plus 1?
Normally, you would do this by finding a pair of numbers whose product is equal to the product of the first term's coefficient multiplied by the last term, and whose sum is equal to the coefficient of the second term. Those numbers could then be used to break the expression down further. In other words, you are looking for two numbers, we'll call them A and B, in which (A + B) = -4 and AB = 5. Unfortunately, there are no such numbers, so that expression can not be factored.
How do you evaluate an expression?
You have to substitute a value for the letter variable in the expression. This is what we call evaluating the algebraic expression. An example would be 3x+1=7, when x=2.
What do you call the number that are multiplied by the variable in an algebraic expression?
factor
