Combining the two equations we came up with in our English-to-equation-translation, we get just such an equation: N_toys = ( W_total – W_towels ) / W_toy We can now turn this abstract solution (abstract in the sense of being written in terms of a bunch of variables) into a numerical solution simply by plugging in numerical values for all the variables on the right side of the equals sign.
I should say that plugging in values isn't always necessary.
If your math homework includes equations, inequalities, functions, polynomials, matrices this is the right trial account. Include everything above plus finding limits (lim), sums, matrices.
Solve all type of trigonometric (sin, cos, tan, sec, scs, cot) expressions, equations, inequalities. Solve integral problems - definite, indefinite integrals.
The most important thing to do when faced with a problem like this is to stop working on it.
Honestly, it sounds paradoxical, but the biggest mistake people make when solving problems is trying to solve them too soon. Make sure you understand exactly what the question is asking and make sure you understand exactly what you are trying to solve for.But (perhaps being a little too clever for your own good) instead of constantly checking this spot, you decide that you'd like to rig up an ingenious system to automatically report to you exactly how many toys are missing.The biggest mistake people make when solving problems is trying to solve them too soon.For example, we don’t actually have numerical values to use in our problem.Which makes sense since our equation was only intended to be used to tell our computer how to convert from total weight to total number of dog toys—we weren’t actually looking for a specific answer to a specific problem.When that number goes above a certain limit, your computer can sound an alarm to let you know that it’s time to go fetch.Now that we have a plan, it's time for the big English-to-equation translation.If the phrase "word problem" sends a shiver down your spine, you're not alone.A lot of people have trouble with so-called word problems in math.Whenever the scale senses a weight increase, it can tell your computer that another toy has been hidden.Your computer can then use some as-yet-unknown equation to figure out exactly how many toys are hidden.
