Introduction

In our previous article, we discussed the basics of subtraction and how to calculate the result of a simple subtraction problem. In this article, we will answer some frequently asked questions about subtraction.

Q: What is the difference between subtraction and addition?

A: Subtraction is the process of finding the difference between two numbers, while addition is the process of finding the sum of two numbers. For example, in the equation 35 - 15, we are finding the difference between 35 and 15, while in the equation 35 + 15, we are finding the sum of 35 and 15.

Q: How do I subtract a negative number from a positive number?

A: To subtract a negative number from a positive number, you need to change the sign of the negative number to positive and then subtract. For example, in the equation 35 - (-15), you need to change the sign of -15 to positive and then subtract, which gives you 35 + 15 = 50.

Q: How do I subtract a decimal number from a whole number?

A: To subtract a decimal number from a whole number, you need to convert the decimal number to a whole number by multiplying it by a power of 10. For example, in the equation 35 - 0.15, you need to multiply 0.15 by 100 to get 15, and then subtract 15 from 35, which gives you 35 - 15 = 20.

Q: Can I subtract a fraction from a whole number?

A: Yes, you can subtract a fraction from a whole number. To do this, you need to convert the fraction to a decimal number by dividing the numerator by the denominator. For example, in the equation 35 - 1/2, you need to convert 1/2 to a decimal number by dividing 1 by 2, which gives you 0.5. Then, you can subtract 0.5 from 35, which gives you 35 - 0.5 = 34.5.

Q: How do I subtract a mixed number from a whole number?

A: To subtract a mixed number from a whole number, you need to convert the mixed number to an improper fraction by multiplying the whole number part by the denominator and adding the numerator. For example, in the equation 35 - 2 1/2, you need to convert 2 1/2 to an improper fraction by multiplying 2 by 2 and adding 1, which gives you 5/2. Then, you can subtract 5/2 from 35, which gives you 35 - 5/2 = 32 1/2.

Q: Can I subtract a negative number from a negative number?

A: Yes, you can subtract a negative number from a negative number. To do this, you need to change the sign of both numbers to positive and then subtract. For example, in the equation -35 - (-15), you need to change the sign of both numbers to positive and then subtract, which gives you 35 - 15 = 20.

Q: How do I subtract a number with multiple decimal places from a whole number?

A: To subtract a number with multiple decimal places from a whole number, you need to convert the number with multiple decimal places to a decimal number by dividing the numerator by the denominator. For example, in the equation 35 - 0.1234, you need to convert 0.1234 to a decimal number by dividing 1234 by 10000, which gives you 0.1234. Then, you can subtract 0.1234 from 35, which gives you 35 - 0.1234 = 34.8766.
