Working from left to right, calculate the numbers in the order shown (without using order of operation).
Replace each question mark with a mathematical sign. Plus, minus, multiply and divide can each be used once only.
In which order should they be used to score 20?
7 ? 4 ? 9 ? 3 ? 5 = 20
The digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 can be arranged into an addition sum to add up to almost any total, except that nobody has yet found a way to add up to 1984. However 9 digits can equal 1984 by an addition sum. Which digit is omitted?
IF 1,3,3=5 9,7,4=8 11,14,10=15 20,16,12=18 Than 3,6,7=?
