Workshop #1 1. Adding a pair of parenthesis can change the outcome of a mathematical computation. For instance the following 3+2·4−5 is equal to 6. However (3 + 2) · 4 − 5 is equal to 15, and 3 + 2 · (4 − 5) is different still! How many different numbers can we get by adding one pair of parenthesis to the following expression 4 + 2 · 3 + 5 · 7 2. Without a calculator, evaluate 2 1 (d) − − 3 4 1 4 (e) · − 7 9 1 2 (f) ÷ 3 4 (a) 8 − (−8) 1 1 − 4 2 5 3 (c) + − 3 5 (b) (g) 1 1 1 1 1 + + + + 2 3 12 20 30 3. Find the area of the following figure: 2 2 4 4. Write a mathematical equation that represents the phrase “Seven is three less than two times x ” 5. Write a mathematical equation that represents the phrase “x is half of one more than y ”
