If a and b are any two real numbers, explain how you calculate the difference a - b. be sure to include the following in your explanation. (a) a description of the relationship between addition and subtraction (b) how you can use a number line to with the calculation (c) how you can determine the sign of the result

- Subtraction can be thought of as the inverse operation of addition, OR as addition itself, if you look at it as adding a negative number.

- The number line allows us to interpret subtraction (or addition of a negative) geometrically; we can view it as a movement to the left on the number line with a distance equal to the number being subtracted.

- Lastly, the value of any expression a - b (where a and b are real numbers) is determined by the relative sizes of the numbers. If a > b, then a - b > 0 (a positive result). If b > a, then a - b < 0 (a negative result.

A=bxh3.2x1.8=5.76 centimeters square

Ihave, but this question is gonna probably get deleted.
