Answer 3

Calculation

To solve the equation 31×29=(30+1)(30-1), we can use the difference of squares formula, which states that a^2 - b^2 = (a + b)(a - b). Applying this formula to the given equation, we get:

31×29 = (30+1)(30-1)

This simplifies to:

31×29 = 31^2 - 1^2

So, the result of the calculation is 31^2 - 1^2.

Result

The result of the calculation 31^2 - 1^2 is 960.
