#TRICK1Here is the trick for determining square of a two-digit number....let's suppose number is "x y"....last digit of your answer is "y square"...Second last digit of your answer is "2*x*y"first digit of your answer is "x square"....adjust

###### A cell phone and phone case cost $210 in total. The cell phone costs $200 more than the phone case. How much was the cell phone?

The cell phone is $205.I'll admit it, I cheated - intuitively you want to answer $200, and, if I hadn't read this article a few weeks ago, that might have been my off the cuff answer.A New Twist on a Classic PuzzleIt turns out, people are lazy, and when presented with a complicated problem, they

###### What is an easy and quick way to learn algebra?

I found out that the secret is to undo what the problem is doing. If the problem c - 4 = 12 then undo the addition by doing its opposite, and add + 4 to both sides. On the left it cancels out the negative, and you are left with c = 16.

###### Which measurement system is better, metric or imperial?

Metric, hands down!Imperial is often favoured for being more "human" (e.g. Divisibility by three, positive temperatures), but that's something of a fallacy.We often need small units of measurement... how practical is it, honestly, to do mental arithmetic with fractions of an inch vs millimetres? Knowing you can divide a foot easily by three is

###### A man's age after 15 years will be the square of his age 15 years ago. What is his present age?

let thee present age be x.(x-15)^2=x+15=>x^2–31*x+210=0=>(x-21)(x-10)=0x=10 or x=21present age can not be 10 as it would result at absurd negative age( -5) 15 years ago.so present age is 21.

###### How can math improve the quality of life?

Math is really helpful in many events.Even the basic 1 to 10 numbers can help you control your short temper.And when it does not work you have binary numbers...So, whenever you are losing your temper, try counting from 1 to 10 in binary.And if it does not work, try binary

###### What are 3 mind blowing facts about math that I probably don't even know?

1. Math is no science. According to classical Pythagorean and Aristotelian definition of science, contemporary math (as it is based on axioms and other arbitrarily chosen assumptions) is a kind of sophistry [two further points are just the simply consequence of this fact].2. You can divide by zero. In this century several mathematical theories appeared, allowing

No science will never be complete without maths, they come in a pair. Somewhere maths can be enough. But except in the field of Biology, maths is required everywhere. An engineer can never develop anything new without mathematics and perfect calculations, similarly in chemistry you need mathematics to develop chemical formula's, etc.

Science is a golden ball... if you want to take it...you need to take a ladder called mathematics. Here I will not take side of either of the subject arguing that one is better than the other because you can't have science without mathematics. You can have mathematics without science but if you don't have science

maybe, maybe not.Their system of mathematics maynot even include addition, subtraction etc.Though the gravitational law, pythogoras theorem are universal, their grasp and perception of it could be fundamentally different.

###### We send messages to outer space for aliens in the form of math, but how can aliens understand if their math is different from ours?

Short answer, it's unlikely that their math is so different from ours that they couldn't figure it out. They may use different symbols and they probably use a different base number system, but those are minor obstacles, the concepts remain the same. If someone has one rock, and picks up another,

###### What math software can I use to write my math book? I will be dealing with plane geometry, graphs, etc. GeoGebra and Scrivener don't give me the experience I want.

I concur about the LaTeX remark. Every math content writer I know has learned LaTeX, so its use is broader than academia. There are lots of simpler programs that can take LaTeX equations now. I think it's even in Google
