There you go Missy Perfection!

15 adults

25 kids

15*5=75

25*3=75

75+75=150

And 40 tickets were sold.....

Whatevs Tiddle!  I answered for you!

I think you missed a huge chunk....

THE TICKETS COLLECTED $150 AND 40 WERE SOLD.  EACH CHILD TICKET IS $3 AND ADULT IS $5

Maybe you'll understand better if the words were in red

That symbol is square root.

The square root of a numer is what one number multiplied by itself equals that number

Like

The square root of 4 is 2, because 2*2=4

Get it?

El signo de la division  en la calculadora es /

$${\frac{{\mathtt{x}}}{{\mathtt{2}}}} = {\mathtt{1}}{\mathtt{\,\small\textbf+\,}}{\frac{\left({\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{x}}{\mathtt{\,-\,}}{\mathtt{4}}\right)}{\left({\mathtt{x}}{\mathtt{\,\small\textbf+\,}}{\mathtt{4}}\right)}} \Rightarrow \left\{ \begin{array}{l}{\mathtt{x}} = {\mathtt{0}}\\
{\mathtt{x}} = {\mathtt{2}}\\
\end{array} \right\}$$

$${\mathtt{8}}{\mathtt{\,-\,}}{\frac{\left({\frac{{\mathtt{3}}}{{\mathtt{4}}}}\right)}{{\mathtt{2}}}}{\mathtt{\,-\,}}\left({\frac{{\mathtt{1}}}{{\mathtt{2}}}}\right) = {\frac{{\mathtt{57}}}{{\mathtt{8}}}} = {\mathtt{7.125}}$$

It doesn't equal 2 1/2

It equals 7 1/8

Well when you add....you, um, include more objects or value to a number

Like.....12+23=35

When adding, you can do this

  12                You add the ones place first!  2+5=7!  Then you add tens!  3+1=4  So 47 is the answer............

+35

47

Always start right and work your way left

11 was in the equation!
