-250
100 + 100, 50+50+50+50, or 120+ 90
x = 50
-50 + 250 (-50) + 250 250 + (-50) 250 - 50 200
say 25x10 you take 20x10 200 then 5x10 50 50 plus 200 equals 250
two hundred plus fifty plus five equals two hundred fifty-five
200 + 50 + 5 = 255
50
-50 plus 50 equals 0
4 times 50 equals 200
50 *4 equals 200, or 25 x 8.
sixty is equal to 10 plus 50, and as 10 equals 50, and 50 equals 79, then it would be fair to assume that 60 equals 50 plus 79, which is 129.
-50 - 200 + 100 + 200 - 150 = -100. Your answer is -100. I hope I've helped you.
