This is the maths I have been working on for the last couple weeks. the strategy is called doubling and halving

46 x 7000=322,000  first you have to double the smallest number which would be 46
and double 46 is 92 so then the equation is now 92 x ?? then halve the biggest number which is 7000
and 1/2 of 7000 is 3500 so now the equation is 92 x 3500 = 322,000.
