How do you work out 35 times by 45?

Answer 1

The answer is 1575.

However, as the question asks "How do you work out 35 x 45", working out would be as follows:

35 x 40, which just 35 x 4 (or 70 x 2) = 140, then place the extra ten on the end: 1400.

Work out 35 x 5, which can be done easily by doing 35 x 10, then halve it, or else just add another 35 to the previous answer of 140. Either way, it is 175.

Add 175 to 1400, and the answer is 1575.
