How does a calculator know the answer straight away?

Question

when given a math problem, i take a little whle to figure it out. but the calculator knows in a flash! How? are there tiny little men hiding in it, who are really good at maths or something? its simply ludicrous!

Answer 1

its a mathematical formula. its programmed in the calculator to spit back the answer to a question. it pluggs in theinfo which u give it and it immediately gives u the answer. like a computer

Answer 2

There are two reasons why a calculator is fast. First, it uses a different system of time than a human. There is a chip on the calculator that acts as a clock. The clock controls the process of the calculator. In the time it takes a person to count to ten, a calculator's clock has already counted to millions. While you are writing down the letters on paper, the calculator has finished with the answer.
The second reason why a calculator is faster is that it uses a different kind of number system (binary) than a human. Our usual 10 = 1010 in binary. A person writes 10x10=100 but a calculator writes :
+1010
+1010
+1010
+1010
+1010
+1010
+1010
+1010
+1010
+1010
=1100100
Then it changes 1100100 into the numbers we use, and prints out 100.
Binary looks complicated but it is actually so simple, a machine can do it. It just has a lot of steps. But a machine's steps are done according to the machine's clock which is much faster than our clock! So the machine is faster than we are.

It's actually TOP SECRET, NATIONAL SECURITY INFO! We would have to kill you if we told you.

Answer 4

it's clever.
