What expression represents the sum of x and negative 11
The expression that represents the sum of x and negative 11 is:
`x + (-11)`
or
`x - 11`
Both of these expressions are equivalent and represent the solution to the problem.
Which expression represents the sum of x and negative 11? (1 point)
The expression that represents the sum of x and negative 11 is:
`x - 11`
or
`x + (-11)`
Both of these expressions are correct and are equivalent.
The expression that represents the sum of x and negative 11 can be written as x + (-11).
To understand why we use (-11) instead of just writing -11, we need to consider the concept of adding a negative number.
When we add a negative number to a positive number, we can think of it as subtraction. So, instead of adding -11, we can subtract 11 from x:
x - 11
However, to represent subtraction using addition, we use the concept of the additive inverse. The additive inverse of a number is the value that, when added to the original number, results in zero.
For example, the additive inverse of 3 is -3, because 3 + (-3) = 0. Similarly, the additive inverse of -11 is 11, because -11 + 11 = 0.
Since we want to represent the subtraction of 11, we can write it as adding the additive inverse, which is (-11).
Therefore, the expression that represents the sum of x and negative 11 is x + (-11).
