Unchanging factor (Constants)

Work Step by Step

In math, an ‘unchanging factor’ is a number in an expression that when the expression is simplified or solved the ‘unchanging factor’ doesn’t change. Another word for an ‘unchanging factor’ is a ‘constant number’. To make this more easier to understand let’s use an example; In the expression 4 + x, 4 is a(n) constant as it doesn’t change (x is a variable). It makes sense that 4 is a constant since it is a number by itself which will not change. As it will not change X doesn’t impact the value of this number, and this is why numbers that don’t change or will remain the same are called constants or unchanging factors.
