# By inserting parenthesis (that is brackets), you can get several values for 2 × 3 + 4 × 5. (For example ((2 × 3) + 5 is one way of inserting parenthesis.) How many such values are there?

The values are

(2 × 3) + 4 = 6 + 4 = 10

3 + ( 4 × 5) = 3 + 20 = 23

2 + (4 × 5) = 2 + 20 = 22

(2 × 3 + 4) × 5 = (6 + 4 ) × 5

= 10 × 5 = 50
