Calculation (19 + 13 / 14) * - 11

The original formula = (20-1 / 14) * (- 11) = - 220 + 11 / 14 = - 219-3 / 14

Seven out of thirteen times thirteen out of fourteen is a simple calculation

4 out of 5 times 5 out of 13 plus 3 out of 5 divided by 13 out of 5 minus 5 out of 13 times 1 out of 5

7 out of 13

3 / 7 times 5 / 13 minus 3 / 7 times 11 / 13 minus 3 / 7 times 3 / 13
Minus 10.5 times [1 / 6 minus 0.5] times 3 / 7 divided by [2 / 6]

3/7×5/13-3/7×(-11/13)-3/7×3/13
＝3/7×(5/13+11/13-3/13)
＝3/7×13/13
＝3/7
-10.5×(1/6-0.5)×3/7÷(-1/2)
＝-10.5×(-1/3)×3/7×(-2)
＝-21/2×1/3×3/7×2
＝-21/7
＝-3
