I'm trying to mentally summarize the names of the operands for basic operations. I've got this so far: Addition: Augend + Addend = Sum. Subtraction: Minuend - Subtrahend = Difference. Multiplicati...
Tex goes between single or double dollar signs. \sqrt for square root, \frac or \dfrac for fractions. Anything longer than one character for formatted input goes in curly brackets {}. For example, \sqrt49 gives $\sqrt49$.
I was confused a bit with a little arithmetic here. For instance $1÷1÷2$ and $2÷3÷7$. BODMAS isn't effective in this case. My question is this: $2÷3÷7$ Am I to divide $2/3$ by $7$ or divide $2$ by ...
It's come to my attention that I don't actually understand what a square root really is (the operation). The only way I know of to take square roots (or nth root, for that matter) it to know the an...
We can multiply $a$ and $n$ by adding $a$ a total of $n$ times. $$ n \\times a = a + a + a + \\cdots +a$$ Can we define division similarly using only addition or ...
There are two differing conventions on how to handle carry-in/out for subtraction. Intel x86 and M68k use a carry-in as "borrow" (1 means subtract 1 more) and adapt their carry-out to mean the same, whereas PowerPC just adds the bitwise-inverted subtrahend plus the carry-in, which inverses the meaning, but is more consistent with the scheme for addition. What convention do you use?
Yonatan: Most of the disagreement anyway is how to handle the case when the digit after the rounding digit is a 5; for the other digits, all seem to be in agreement. I guess the rules are application-dependent!
It is still unclear whether you are looking for a trick, a formula, an algorithm, or a mathematical definition, so I will provide all four. Trick: Probably the easiest way to do this by hand is do long division on $183 / 60$ but throw away the remainder (or remove all the numbers after the decimal point, if you prefer). Formula: This is generally written $\left\lfloor \frac {183} {60} \right ...
