Think about what the results would be for the following expressions, and then type them in to verify your answers

25 / 5 * 5

4 + 3 ^ 2

(4 + 3) ^ 2

3 \ 12 + 5

4 – 2 * 3

>> 25/5*5

ans = 25

>> 4 + 3 ^ 2

ans = 13

>> (4 + 3) ^ 2

ans = 49

>> 3 \ 12 + 5

ans = 9

>> 4 - 2 * 3

ans = -2

As the world becomes more “flat”, it is increasingly important for engineers and scientists to be able to work with colleagues in other parts of the world. Correct conversion of data from one system of units to another (for example, from the metric system to the American system or vice versa) is critically important.
