Hope an expert can with both answers on here thanx

All you got to do is take to the numbers until there's no more numbers if there's an extra one out of three number one and then you go and you X all of them and then once you do that take with the leftover numbers and then you add them all and you should get your answer it's going to be a big one though

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
