Wow ! If I understand what's go0ing on here, then
we have to be careful, and THINK .
I was going to ask you "What does Ф mean ?", and then I realized,
Ф is a new operation that the teacher invented.
The first line on the board is the definition of Ф .
Ф means "<u>Add the two numbers and subtract 4</u>."
Now you have to use this new invention to find the value
of the second line:
Take care of the stuff inside the parentheses first: ( 4 Ф 2 )
<u>Add the two numbers and subtract 4
</u>4 + 2 - 4 = <u>2</u><u>
</u>That's the part inside the parentheses. It's <span><u>2</u> .</span><u>
</u>NOW, we have to do the new operation with the 2 inside,
and the 3 that's outside the parentheses:<u>
</u>3 Ф 2
<u>Add the two numbers and subtract 4</u>
3 + 2 - 4 =<u> 1</u>
And that's the final value of 3 Ф (4 Ф 2) . It's <u>1</u> .
Pretty sneaky.
