Hello KS,

Please don't keel over in shock at seeing my name in response to one of your problems!

Well, I took my calculator and did a few computations. Would you believe it? I found one solution quite quickly!

Here it is

6^3 - 5^3 = 91

(6*5)+ 61 = 91

Thanks for an interesting problem.:) Josie
