One arithmetic problem -4.25 times 4 and 6 / 5 minus 4.25 times 6 and 6 / 1 plus 4 and 4 / 4 / 1. Simple algorithm

One arithmetic problem -4.25 times 4 and 6 / 5 minus 4.25 times 6 and 6 / 1 plus 4 and 4 / 4 / 1. Simple algorithm

Original formula = - 4.25 × 29 / 6-4.25 × 37 / 6 + 17 / 4
=-4.25×(29/6+37/6)+4.25
=-4.25×11+4.25
=-4.25×(11-1)
=-4.25×10
=-42.5
