By adding the smallest two digit number and the largest two digit number, how much should be subtracted to make it one hundred? We can approach this problem using algebra. Let x be the smallest two-digit number, and y be the largest two-digit number. Then we can write: x + y = 10 + 99 = 109 We want to find a value z such that: x + y - z = 100 Substituting the value of x + y from the first equation, we get: 109 - z = 100 Solving for z, we get: z = 109 - 100 = 9 Therefore, we need to subtract 9 from the sum of the smallest two-digit number and the largest two-digit number to make it equal to 100.

We can approach this problem using algebra. Let x be the smallest two-digit number, and y be the largest two-digit number. Then we can write:
x + y = 10 + 99 = 109
We want to find a value z such that:
x + y - z = 100
Substituting the value of x + y from the first equation, we get:
109 - z = 100
Solving for z, we get:
z = 109 - 100 = 9
Therefore, we need to subtract 9 from the sum of the smallest two-digit number and the largest two-digit number to make it equal to 100.
another solution
The smallest two-digit number is 10, and the largest two-digit number is 99.
When we add these two numbers, we get:
10 + 99 = 109
To make the sum equal to 100, we need to subtract the difference between the sum and 100, i.e.,
109 - 100 = 9
Therefore, we need to subtract 9 from the sum of the smallest two-digit number and the largest two-digit number to make it equal to 100.
