bottle = 30/3 = 10
burger = (20 - 10)/2 = 5
pair-of-pints = (9 - 5)/2 = 2
so assuming single-pint = pair-of-pints/2 = 1, we compute:
burger + single-pint x bottle = 5 + 1 x 10 = 15

assume we are in R
for sure it's a = 10, b = 5, c = 2

>> No.8470053

>>8470036
order of operations are only used when parentheses are absent. They should always be used. It's good practice especially in preparation for programs such as Excel or Matlab

Teaching order of operations instead of the use of parentheses is silly. They remove all ambiguity

Why would the two-beers symbol mean twice instead of square? Let's try this:
[eqn]\begin{cases} 3\,x \,=\, 30 \\ x \,+\, 2\,y \,=\, 20 \\ y \,+\, 2\,z^2 \,=\, 9 \end{cases} \quad\text{iff}\quad \begin{cases} x \,=\, 10 \\ 2\,y \,=\, 10 \\ y \,+\, 2\,z^2 \,=\, 9 \end{cases} \quad\text{iff}\quad \begin{cases} x \,=\, 10 \\ y \,=\, 5 \\ z^2 \,=\, 2 \end{cases}[/eqn]
1st case: [math]z \=\, \sqrt{2}[/math] then [math]y \,+\, z\,x \,=\, 5 \,+\, 10\,\sqrt{2} \,=\, 5\,\left( 1 \,+\, 2\,\sqrt{2} \right)[/math].
2nd case: [math]z \,=\, -\sqrt{2}[/math] then [math]y \,+\, z\,x \,=\, 5 \,-\, 10\,\sqrt{2} \,=\, 5\,\left( 1 \,-\, 2\,\sqrt{2} \right)[/math].
Thus [math]y \,+\, z\,x \,\in\, \left\{ 5\,\left( 1 \,-\, 2\,\sqrt{2} \right),\, 5\,\left( 1 \,+\, 2\,\sqrt{2} \right) \right\}[/math].
