That depends on the answer required.
If it's 11 then each digit can be made from 3 sticks
9 + 11 = 20... 19 - 4 = 15... 15 x 20 = 300... 300 - 6 = 294 !
5 + 6 = 11 6 + 5 = 11 11 - 6 = 5 11 - 5 = 6
11 + (19 + 6) = 36(11 + 19) + 6 = 36So they are both equal. The brackets make no difference in this case.
Yes, it is possible to make 25 cents with 17 coins. You can achieve this by using 6 quarters (6 x 25 cents = 150 cents) and 11 pennies (11 x 1 cent = 11 cents). In total, you would have 17 coins with a combined value of 25 cents.
11 is a prime number and has no prime factors other than itself.
You take 6 and make a rectangle which is a square and take one of the 5 sticks break it in 2 to make 6 which you can make another square or rectangle easy
3x4=12x6=72-6=66-6=60
6+6-1=11
You can make 9 triangles but NOT rectangles.
9 + 11 = 20... 19 - 4 = 15... 15 x 20 = 300... 300 - 6 = 294 !
ooh 11-8=3 3*10=30 30-6=24 tadaa this one took me some thinking
One possibility - I'm sure there are others, is : 32 + 8 - 6 = 9 + 2 = 11
put sticks in 6 boxes but keep the top emty
By using all six match sticks only once the maximum number of Roman numerals that can be made are three i.e. I, II and III (1, 2 and 3).
4'6'' = 54'' 54'' / 4'' = 13.5 Therefore, 13.5 x 4'' sticks would make 4'6''.
If you know that, 6 x 11 = 66, then this can be rearranged to make 66/11 = 6
2*(6/6 + 11) = 2*(1 + 11) = 2*12 = 24. Simple!
