What is a multimeter?
“A multimeter measures electrical properties such as AC or DC voltage, current, and resistance. Rather than have separate meters, this device combines a voltemeter, an ammeter, and an hommeter. Electricians and the general public might use it on batteries, components, switches, power sources, and motors to diagnose electrical malfunctions and narrow down their cause.”(http://www.wisegeek.org/whatisamultimeter.htm#multimeterisolated)

What is the difference among BINARY, HEXADECIMAL, and DECIMAL?
“Binary: Binary numbers are just “Base 2” instead of “Base 10”. So you start counting at 0, then 1, then you run out of digits … so you start back at 0 again, but increase the number on the left by 1.
Decimal: To understand Binary and Hexadecimal numbers, it is best to know how Decimal numbers work. Every digit in a decimal number has a “position”, and the decimal point helps us to know which position is which.
Hexadecimal: There are 16 of them. They look the same as the decimal numbers up to 9, but then there are the letters (“A’,”B”,”C”,”D”,”E”,”F”) in place of the decimal numbers 10 to 15. So a single Hexadecimal digit can show 16 different values instead of the normal 10 like this:”
Decimal:  0  1  2  3  4  5  6  7  8  9  10  11  12  13  14  15 

Hexadecimal:  0  1  2  3  4  5  6  7  8  9  A  B  C  D  E  F

What is the difference between inductive and deductive logic?
“Inductive and inductive reasoning are both approaches that can be used to evaluate inferences. Deductive reasoning involves starting out with a theory or general statement, then moving towards a specific conclusion.Indeductive reasoning on the other hand, takes a series of specific observations and tries to expand them into a more general theory. Each approach is very different, and it is important to be aware that both inductive and deductive reasoning can end up with false results, especially if the initial premise of the reasoning is false, in which case the results are said to be “unsound.””

What did you think about Honors Academy, Exploratory Math?
I think that was very interesting and fun. I met a lot of different people from other schools and teachers from other countries. I really liked this experice, is my very first time that I’ve been in a summer course. I hope I go to Stanford next year 🙂
