Mathway Free Math Solver

  Tip : Refresh your browser if it doesn’t load the first time. Trust me, it happens.

I must say that there is no alternative to paying attention in class, writing down notes, studying at home, and doing a lot of independent practice using pencil and paper. However, there are times when a teacher or tutor is not available to help you solve a math problem. This can be frustrating at times. But, don’t worry. Mathway can be that extra “eye” to help double-check your work. Whether it’s math homework in pre-algebra, algebra, geometry, trigonometry, precalculus, statistics, or calculus, this is the tool for you. Heck, you can even just use it as a regular arithmetic calculator! Moreover, you can also use this as a graphing utility to graph any functions such as linear, quadratic, trigonometric functions, etc. To be honest, I start wondering what this math solver cannot do!

Mathway’s math problem solver is an excellent tool to check your work for free. Just type in the math problem into the interactive calculator using its prescribed syntax, and it will give you the correct answer. It’s like having a private tutor 24/7/365 with you at all times!

Note: If you want more help, and therefore, would want to see how Mathway solves the problem step by step, you can click “Tap to view steps…” to redirect you to the developer’s website for a modest subscription fee which in return, I will receive some monetary compensation .

However, if what you need is to simply check if you arrived at the correct answer and not necessarily detailed step-by-step answers, then the widget should be sufficient for you.

A soccer coach wants to know how many hours a week his players spend training at home. He has 20 players and he decides to ask the first 4 players to arrive at Monday's soccer practice how many hours they spend training per week. He then calculated that they spend an average of 10 hour per week. Therefore, he assumed that all the players train 10 hours per week. Is this an example of a simple random sample? 

A No, because each student did not have an equal chance of being selected. 

B Yes, because each student had an equal chance of being selected. 

C No, because he did not sample every soccer player. 

D Yes, the minimum number of students sampled need to be four for it to be a simple random sample.

A health psychologist was interested in the effects of vitamin supplements on the immune system. Three groups of adults were exposed (in a highly ethical way) to the cold virus; one group took no supplements for a week before exposure, another had vitamin C supplements, and a third had multivitamins (excluding C). The severity of the cold was measured as a percentage (0% = not contracted, 100% very severe symptoms). The psychologist also measured the number of cigarettes that each person smoked per day, as smoking suppresses the immune system. The psychologist was interested in the differences in the severity of the illnesses across different vitamin groups accounting for cigarette usage.
