To find the value of 119 squared minus 111 squared, we can use the formula for finding the difference of squares. The formula states that the square of the difference between two numbers, a and b, can be calculated by multiplying the sum of a and b with the difference between the two numbers.
In this case, a = 119 and b = 111. Therefore, we can calculate the value of the expression (119^2 - 111^2) as follows:
1. Calculate the sum of 119 and 111: 119 + 111 = 230
2. Calculate the difference between 119 and 111: 119 - 111 = 8
3. Multiply the sum and difference obtained from step 1 and 2: 230 * 8 = 1840
Hence, the value of 119 squared minus 111 squared is 1840.
