How much less than -2 is -6?

To find any number less than a given number, we use the mathematical operation called subtraction

Answer: 4 less than -2 is -6.

We can always subtract an integer from a given integer and the result is again an integer

Explanation:

Let us consider that 'x' less than -2 is -6. Let us now write this as an equation as:

-2 - x = -6

or, -2 - x + 2 = -6 + 2 (Adding 2 to both sides of the equation)

or, - x = - 4 

or, x = 4

Therefore, 4 less than -2 is -6.
