-17 + 3

= 3 - 17

= -14

10 + 41 x 12

= 10 + 492

= 502

Wow soo much points xD

Guest #1: LOL?

f(-x)= 2x^2 + 4x + 6 

f(-x)= -(-2x^2 - 4x - 6)

f(x) = -2x^2 - 4x - 6

$(6x^2y+4xy^2-2y^3+6)+(x^2y+3y^3-5)\\ = 6x^2y+4xy^2-2y^3+6+x^2y+3y^3-5\\ =7x^2y+4xy^2+y^3+1\\ \text{Same as geno's answer}$

$\dfrac{21}{2}\div\dfrac{3}{1}\\ = \dfrac{21}{2}\times \dfrac{1}{3}\\ = \dfrac{\not{21}^7}{2}\times \dfrac{1}{\not3}\\ =\dfrac{7}{2}$

EG: $\dfrac{\log 5}{\log e}= \ln 5\\ \dfrac{\log 2}{\log 1000}=\log_{1000}2$

1 ounce =28.3495231 gram

Therefore price for 1 gram = 150/28.3495231 which is about $5.36

Notice this is approximated value. Same as Guest #1's answer.

$\dfrac{22500}{3190000}\times 100 \%\\ = \dfrac{2250000}{3190000}\%\\ =\dfrac{225}{319}\%\\ \approx0.7053291536050157\%$

$\text{Fractions are of the form }\dfrac{a}{b}\text{ and that just means }a\div b\\ \text{Example:}\dfrac{7}{5}= 7\div 5 = 1.4$
