$10x+5$ is of order 1 and has two terms

7 lots of $x$ plus 3 lots of $x$ is a total count of 10 lots of $x$

Write as: $" " 10x+5$

Consider the following example

$a " "$ is the same as $a^1$ and is of order 1
$axxa" "$ is the same as $a^2$ and is of order 2
$axxaxxa" "$ is the same as $a^3$ and is of order 3

So

$10x+5$ is of order 1 and has two terms
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Just to make it really clear
If your expression hade been $10x^2+5$ then it would have been of order 2

How do you write a polynomial in standard form, then classify it by degree and number of terms 7x+3x+5 7x+3x+5?
