The given expression is 2-8.
Write the subtraction in term of addition as,
a-b=a+(-b)
The given expression becomes,
2-8=2+(-8)
Now, the given two values are of different signs and for the addition of any two numbers of different signs, subtract the smaller absolute value from the larger absolute value.
Absolute values of the numbers are,
|2|=2
|-8|=8
The number -8 has larger absolute value, so subtract 2 from 8.
8-2=6
As the largest number 8 is negative, the answer is also negative
So, the difference of the given expression is -6.
Final statement:
Therefore, the simplified form of the expression 2-8 is -6.
