Make 44 only with the use of 6 , 7 , 8 , 9 and addition , subtraction , multiplication , division. Each of the numbers 6 , 7 , 8 , 9 has to be used exactly
once and any of the four basic operations can be used any number of times.
thanks in advance

@fobvius,
44/8= 22/4= 11/2= 5 1/2

Then divide nine by six

@raprap,
44 = 8 x 7 - 8 x 9 / 6

@uvosky,
44/8=5 1/5
5 1/2=7-1 1/2=7-9/6
44=(7-9/6)*8

@raprap,
Thanks rap for correcting , 44 = 7*8 - 9*8/6 would not be right because it uses 8 twice , which is not allowed. The 44= ( 7 - 9 / 6 )*8 that you gave seems to be correct , but still can you find a solution without using parenthesis ?
