How to calculate the mixed operation of positive and negative numbers in mathematics 1. Positive 3 and 5 / 6 plus negative 1 and 3 / 4 minus 5 and 1 / 6 minus 3.25 2. Two thirds of negative zero 125 times negative three fifths times negative eight times positive one 3. Minus the square of three minus the cubic of three minus the square of two minus the square of two I have to hand it in tomorrow,

A: original formula = 23 / 6-7 / 4 + 31 / 6-13 / 4 = (31 / 6 + 23 / 6) - (7 / 4 + 13 / 4) = 9-5 = 4 & # 10103; original formula = (- 1 / 8) × (- 8) × (- 3 / 5) × (5 / 3) = 1 × (- 1)
