Well, isn't that a happy little math problem! If you take a moment to think about it, you'll see that 5 times 8 equals 40, and if we add just a little more, we get to 42. So, the answer is 5 times 8! Just remember, there are many ways to reach your answer, and each one is a beautiful journey of discovery.
42 times 2 equals 84.
20/21 times 42 = 40
42 x 2 = 84
1/2 times 42 = 21
6 x 7
2 x 7 x 42 = 588
The numbers are: 42+ 7 times sq rt of 30 and 42- 7 times sq rt of 30
42 ÷ 2 = 21
42 because 21 times 2 is 42 and 14 times 3 is 42
42 divided by 7 times 2 is equal to 12.
How about: 2 times 21 = 42
