Final answer:
To find the result of -513 - 213, consider that subtracting a positive from a negative is like adding two negatives, thus giving the answer -726. the correct answer to the problem -513 - 213 is b) -726.
Step-by-step explanation:
To subtract the numbers -513 and 213, one needs to understand the rules of subtraction involving negative numbers. By subtracting a positive number from a negative number, you are effectively adding the absolute value of the positive number to the already negative number, thus making the result even more negative. Therefore, -513 - 213 is the same as -513 + (-213), which equals -726.
To solve the subtraction problem -513 - 213, follow these steps: 1. Understand the numbers: You have two negative numbers.
The first number is -513 and you're subtracting 213 from it. 2. Apply the subtraction rules: Subtracting a positive number from a negative number is the same as adding another negative number.
So the equation -513 - 213 is equivalent to -513 + (-213). 3. Combine the numbers: When you are adding two negative numbers, you combine their absolute values (the number without the negative sign) and keep the negative sign.
So you add 513 and 213. 4. Calculate the sum of the absolute values: 513 + 213 = 726. 5. Attach the negative sign: Since both numbers you're combining are negative, the result will also be negative. Therefore, -513 + (-213) equals -726. So the correct answer to the problem -513 - 213 is b) -726.
