In math, when you subtract a negative number from another negative number, it is similar to adding a positive number.
Let's consider the example you provided: -38 - (-14).
To understand the solution, we can follow these steps:
1. Keep the first number (-38) as it is.
2. Change the subtraction of a negative number (-14) to addition of a positive number (+14).
3. Perform the addition: -38 + 14.
The result is -24.
Now, let's go through the rules for multiplying, dividing, adding, and subtracting:
1. Adding:
- Adding two positive numbers: When you add two positive numbers, you simply add them together. For example, 5 + 3 = 8.
- Adding two negative numbers: When you add two negative numbers, you also add them together. For example, -5 + (-3) = -8.
- Adding a positive number and a negative number: When you add a positive number and a negative number, you subtract the smaller absolute value from the larger one and take the sign of the number with the greater absolute value. For example, 5 + (-3) = 2 or -5 + 3 = -2.
2. Subtracting:
- Subtracting a positive number from a positive number: When you subtract a positive number from a positive number, you subtract the smaller number from the larger one. For example, 8 - 3 = 5.
- Subtracting a negative number from a positive number: When you subtract a negative number from a positive number, it is similar to adding a positive number. For example, 8 - (-3) is the same as 8 + 3 = 11.
- Subtracting a positive number from a negative number: When you subtract a positive number from a negative number, it is similar to adding a negative number. For example, -8 - 3 is the same as -8 + (-3) = -11.
- Subtracting a negative number from a negative number: When you subtract a negative number from a negative number, it is similar to adding a positive number. For example, -8 - (-3) is the same as -8 + 3 = -5.
3. Multiplying:
- Multiplying two positive numbers: When you multiply two positive numbers, you simply multiply them together. For example, 4 * 3 = 12.
- Multiplying two negative numbers: When you multiply two negative numbers, the product is positive. For example, (-4) * (-3) = 12.
- Multiplying a positive number and a negative number: When you multiply a positive number and a negative number, the product is negative. For example, 4 * (-3) = -12.
4. Dividing:
- Dividing a positive number by a positive number: When you divide a positive number by a positive number, you obtain a positive result. For example, 12 / 3 = 4.
- Dividing a negative number by a positive number: When you divide a negative number by a positive number, you obtain a negative result. For example, -12 / 3 = -4.
- Dividing a positive number by a negative number: When you divide a positive number by a negative number, you obtain a negative result. For example, 12 / (-3) = -4.
- Dividing a negative number by a negative number: When you divide a negative number by a negative number, you obtain a positive result. For example, -12 / (-3) = 4.
These are the basic rules for performing arithmetic operations with positive and negative numbers.
