So let’s try this;
2319(÷, ×, ±) 74 , D1/D2, R2
31 time 2 =62, 62 plus 2=64, 64 plus 9=73, 73 plus 1=74
We have used double digits (D2)and single digits(D1) as advised in D1/D2, and no number has been used more than twice (R2). And our answer is 74.
Please remember this is just a game, and you may create your own random numbers and solve or give it to your friend as a quiz.
I will leave it at that level of and develop the second component in the next post. Thanks.
