Below are pictured 5 coins (represented by X and O). Your job is to get the 3 X's together and the 2 O's together by sliding the coins. You must slide two coins at a time, an X and an O. They must move together as a unit. You cannot move them further apart or closer together, and you cannot turn them around, that is turn XO into OX or OX into XO. You also cannot spread the 3 remaining coins apart or push them closer together. The coins must end up in a straight line with no gaps. It can be done in just 3 moves. Can you find them? X O X O X
i thing these three step's are 1. X 0 X X 0 2. X X 0 X 0 3. X X X 0 0 pl confirm it's right or 00000!
Darkness You cann't move any two object at once. after X 0 X X 0 you direct say X X X 0 0 (Who? one step is missing)
ok ok ok lol you win! women :p joke joke hmm a dnt know tbh, cuz we have to get rid of spaces and we have to move X n O together well a cud b wrong who knows lolz can we get the answer please :]
Multiply Up to 20X20 In Your Head In just FIVE minutes you should learn to quickly multiply up to 20x20 in your head. With this trick, you will be able to multiply any two numbers from 11 to 19 in your head quickly, without the use of a calculator. I will assume that you know your multiplication table reasonably well up to 10x10. Try this: Take 15 x 13 for an example. Always place the larger number of the two on top in your mind. Then draw the shape of Africa mentally so it covers the 15 and the 3 from the 13 below. Those covered numbers are all you need. First add 15 + 3 = 18 Add a zero behind it (multiply by 10) to get 180. Multiply the covered lower 3 x the single digit above it the "5" (3x5= 15) Add 180 + 15 = 195. That is It! Wasn't that easy? Practice it on paper first! (Reference angelfire)
