This summer, battle lines were drawn over a simple math problem: 8 ÷ 2(2 + 2) = ? If you divide 8 by 2 first, you get 16, but if you multiply 2 by (2 + 2) first, you get 1. So, which answer is right?

To multiply \(23.7\) by \(4\) without using a calculator, you can set it out like this: One decimal place is used in the calculation therefore the solution should also contain one decimal place.
