Certain words indicate certain mathematica operations. But the order in addition doesn't matter, so it's okay to add backwards, because the result will be the same either way.) Also note that order is important in the "quotient/ratio of" and "difference between/of" constructions.If a problems says "the ratio of Some times, you'll be expected to bring your "real world" knowledge to an exercise.But figuring out the actual equation can seem nearly impossible. Be advised, however: To learn "how to do" word problems, you will need to practice, practice, practice.The first step to effectively translating and solving word problems is to read the problem entirely.Tags: fraction, percent, pie Calculates a total downward distance traveled given an initial height of a drop and a rebound ratio percentage Features: Calculator | Practice Problem Generator | Watch the Video Tags: distance, percentage, ratio Determines a necessary amount of a Solution given two solution percentages and 1 solution amount.Features: Calculator | Practice Problem Generator Examples (1): how much pure acid should be added to 18 L of 30% acid to increase the concentration of 50% acid?Tags: mixture, solution Given an initial principal amount, interest rate on Fund 1, interest rate on Fund 2, and a total interest paid, calculates the amount invested in each fund.Features: Calculator | Practice Problem Generator Tags: interest, principal Determines the sum of the first (n) * Whole Numbers * Natural Numbers * Even Numbers * Odd Numbers * Square Numbers * Cube Numbers * Fourth Power Numbers Features: Calculator | Quiz Generator | Practice Problem Generator | Watch the Video Examples (5): sum of the first 9 natural numbers, what is the sum of the first 10 cube numbers, show sum of the first 10 square numbers, sum first 15 even numbers, sum first 18 odd numbers Tags: shortcut sums, sum of integers Given Person or Object A doing a job in (r) units of time and Person or Object B doing a job in (s) units of time, this calculates how long it would take if they combined to do the job.
