Use the additive inverse to find −1223−(−856). Write the answer as a mixed number.
the answer is not -367
naw what's going on here.
To find the sum of two numbers using the additive inverse, we can change the subtraction into addition and change the sign of the second number.
The given expression is −1223−(−856).
To change subtraction into addition, we can rewrite the expression as −1223+(−856).
To find the additive inverse of −856, we change the sign, which gives us +856.
Now we can add the two numbers:
−1223 + (+856) = −367.
The answer is −367.
To find the sum of two numbers using the additive inverse, you can add the opposite of the second number to the first number.
In this case, we want to find −1223 − (−856). The opposite of −856 is 856. So, we can rewrite the expression as −1223 + 856.
Now, we can add these two numbers:
-1223 + 856 = -367
Therefore, the answer is -367.
To write it as a mixed number, we need to express it as a whole number and a fraction. Since the number is negative, we can write it as -367 and it already represents a whole number. So, there is no need to write it as a mixed number in this case.
The additive inverse of a number is the opposite of that number. To find the additive inverse of −856, we change the sign of the number to positive, giving us 856.
Now, we can rewrite the expression as −1223 + 856.
When we subtract 856 from -1223, we get -1223 + 856 = -367.
Therefore, the answer is -367, which can also be written as a mixed number as -366 1/3 (where 1/3 is the fraction part of the mixed number).
