Use the additive inverse to find −123.45−(−234.76).
To find the sum of −123.45−(−234.76) using the additive inverse, we can rewrite the expression as -123.45 + 234.76. By doing this, we change the subtraction operation to addition with the additive inverse.
Now, we can add -123.45 and 234.76 together:
-123.45 + 234.76 = 111.31
Therefore, −123.45−(−234.76) is equal to 111.31.
Use the additive inverse to find −2445−671
Use the additive inverse to find −24 4/5−6 7/10
To find the value of -123.45 - (-234.76) using the additive inverse, we can rewrite the expression as -123.45 + 234.76.
First, find the additive inverse of -123.45:
The additive inverse of a number is the number that when added to the original number will give a sum of zero. In this case, the additive inverse of -123.45 is 123.45.
Next, add the additive inverse to the second number:
123.45 + 234.76 = 358.21
Therefore, -123.45 - (-234.76) is equal to 358.21.
To find the difference between two numbers, you can use the additive inverse or the concept of changing the sign and adding. The additive inverse of a number is the number that, when added to the original number, yields a sum of zero.
In this case, we are given the expression -123.45 - (-234.76). The first step is to change the sign of the second number to its additive inverse. To do this, we need to remember that changing the sign of a number means multiplying it by -1.
So, the additive inverse of -234.76 is -1 * -234.76, which equals 234.76. Therefore, the expression simplifies to -123.45 + 234.76.
Next, we add the two numbers -123.45 and 234.76 together:
-123.45 + 234.76 = 111.31
Therefore, the value of -123.45 - (-234.76) is 111.31.
