Long formulas may be given in 2 or more lines by breaking them at operation signs outside brackets or parentheses and keeping the indention the same whenever possible (some formulas may be too long to permit indention). If lines begin with an operation sign, they should be lined up with the first character to the right of the relation sign in the line above.Y=[(a1+b1)/(a2−b2)]+[(σ1+σ2)/(σ2−σ1)]+[(s1+s2)/(t1+t2)] However, if a formula loses comprehensibility by being unstacked and broken up, and/or if it fits the width of the column, it is preferable to leave it stacked.Percent Excess Weight Loss =(Baseline Weight − Ideal Weight)−(Follow-up − Ideal Weight)Baseline Weight − Ideal Weight×100
