**To perform type B function, press the above function key(s) then
input calculation value
7) Abbreviated multiplication format in front of Type B functions :
2 3, Alog2, etc.
8) Permutations (nPr) and combinations (nCr).
9) x,
10) +,
Operations of the same precedence are performed from right to left.
For example: e
x
ln 120 e
x
{ln( 120)}. Other operations are
performed from left to right
Operations enclosed with parentheses are performed first. When a
calculation contains an argument that is a negative number, the
negative number must be enclosed within parentheses.
Example:
(-2)
4
= 16; and -2
4
= -16
