find the sum or difference. write the answer in simplest form.

W=FxD

W= 15N x 5m
W=45 J

To find the sum or difference of two numbers, you first need to know whether you are adding or subtracting the numbers.

If you are adding two or more numbers, you simply add them together to find the sum. For example, if you want to find the sum of 5, 8, and 3, you add them: 5 + 8 + 3 = 16. The sum in this example is 16.

If you are subtracting numbers, you subtract the second number from the first to find the difference. For example, if you want to find the difference between 10 and 6, you subtract 6 from 10: 10 - 6 = 4. The difference in this example is 4.

You mentioned writing the answer in simplest form. This typically refers to fractions. If the question involves fractions, you may need to simplify the fraction to its lowest terms. To do this, you find the greatest common divisor (GCD) of the numerator and denominator, and divide both by the GCD. For example, if you want to simplify the fraction 6/12, the GCD of 6 and 12 is 6, so you divide both the numerator and denominator by 6, resulting in 1/2. The simplest form of 6/12 is 1/2.

Please provide specific numbers or examples if you have a particular calculation in mind.
