I just typed it into a calculator

Answer 4

you do 36/4.3 first then subtract -25

Answer 5

use PEMDAS Please

Answer 6

There are no ( ) or exponents so move on to Division and Multiplication 36/4.3 which is 8.37. Then move on to Addition and Subtraction there is no adding so you subtract negative 25 which you cannot subtract a negative so you add the 25 NOT subtract it. So 8.37 plus 25 is 33.37

Get it?

Answer 7

it is 52
Use * for multiplication, / for division, and ^ for exponentiation. You can also use math functions such as sqrt() exp(), ln(), cos() and sin(). Also, ch(n, k) will evaluate "n choose k". For example, ch(4,2) = 6
fac(n) is n! - so for example, fac(4) = 24.
Finally, you can sum a series with the sigma command.
For example, sigma[2, 6,1/k^2] evaluates the sum from k=2 to k=6 of the expression 1/k^2.
Note that [ ]'s are used in sigma and not parentheses. The summation variable must be k.
