&lt;b&gt;5m+3n+p, -5p+3n, &lt;/b&gt;and&lt;b&gt; 2n-m&lt;/b&gt;

Put a &lt;b&gt;1&lt;/b&gt; in front of the two letters which do 
not have a number in front of them.

&lt;b&gt;5m+3n+1p, -5p+3n, &lt;/b&gt;and&lt;b&gt; 2n-1m&lt;/b&gt;

2. Put a &lt;b&gt;+&lt;/b&gt; sign in front of the two expressions which do 
not have a sign in front of them.

&lt;b&gt;+5m+3n+1p, -5p+3n, &lt;/b&gt;and&lt;b&gt; +2n-1m&lt;/b&gt;

Color every term, the number and the sign before it, 
if any:

1. &lt;font color=&quot;red&quot;&gt;&lt;b&gt;red&lt;/font&gt;&lt;/b&gt; if it contains the letter &quot;&lt;font color=&quot;red&quot;&gt;&lt;b&gt;m&lt;/font&gt;&lt;/b&gt;&quot;.
2. &lt;font color=&quot;blue&quot;&gt;&lt;b&gt;blue&lt;/font&gt;&lt;/b&gt; if it contains the letter &quot;&lt;font color=&quot;blue&quot;&gt;&lt;b&gt;n&lt;/font&gt;&lt;/b&gt;&quot;.
3. &lt;font color=&quot;green&quot;&gt;&lt;b&gt;green&lt;/font&gt;&lt;/b&gt; if it contains the letter &quot;&lt;font color=&quot;green&quot;&gt;&lt;b&gt;p&lt;/font&gt;&lt;/b&gt;&quot;.

&lt;font color=&quot;red&quot;&gt;&lt;b&gt;5m&lt;/font&gt;&lt;/b&gt;&lt;font color=&quot;blue&quot;&gt;&lt;b&gt;+3n&lt;/font&gt;&lt;/b&gt;&lt;font color=&quot;green&quot;&gt;&lt;b&gt;+1p&lt;/font&gt;&lt;/b&gt;, &lt;font color=&quot;green&quot;&gt;&lt;b&gt;-5p&lt;/font&gt;&lt;/b&gt;&lt;font color=&quot;blue&quot;&gt;&lt;b&gt;+3n&lt;/font&gt;&lt;/b&gt;, and &lt;font color=&quot;blue&quot;&gt;&lt;b&gt;2n&lt;/font&gt;&lt;/b&gt;&lt;font color=&quot;red&quot;&gt;&lt;b&gt;-1m&lt;/font&gt;&lt;/b&gt;

We combine both &lt;font color=&quot;red&quot;&gt;&lt;b&gt;red&lt;/font&gt;&lt;/b&gt; terms:

&lt;font color=&quot;red&quot;&gt;&lt;b&gt;+5m&lt;/font&gt;&lt;/b&gt;&lt;font color=&quot;red&quot;&gt;&lt;b&gt;-1m&lt;/font&gt;&lt;/b&gt;, which gives &lt;font color=&quot;red&quot;&gt;&lt;b&gt;+4m&lt;/font&gt;&lt;/b&gt; 

&lt;/b&gt;We combine all three &lt;font color=&quot;blue&quot;&gt;&lt;b&gt;blue&lt;/font&gt;&lt;/b&gt; terms:

&lt;font color=&quot;blue&quot;&gt;&lt;b&gt;+3n&lt;/font&gt;&lt;/b&gt;&lt;font color=&quot;blue&quot;&gt;&lt;b&gt;+3n&lt;/font&gt;&lt;/b&gt;&lt;font color=&quot;blue&quot;&gt;&lt;b&gt;+2n&lt;/font&gt;&lt;/b&gt;, which gives &lt;font color=&quot;blue&quot;&gt;&lt;b&gt;+8n&lt;/font&gt;&lt;/b&gt;

We combine both &lt;font color=&quot;green&quot;&gt;&lt;b&gt;green&lt;/font&gt;&lt;/b&gt; terms:

&lt;font color=&quot;green&quot;&gt;&lt;b&gt;+1p&lt;/font&gt;&lt;/b&gt;&lt;font color=&quot;green&quot;&gt;&lt;b&gt;-5p&lt;/font&gt;&lt;/b&gt;, which gives &lt;font color=&quot;green&quot;&gt;&lt;b&gt;-4p&lt;/font&gt;&lt;/b&gt; 

We put them together:

&lt;font color=&quot;red&quot;&gt;&lt;b&gt;+4m&lt;/font&gt;&lt;/b&gt;&lt;font color=&quot;blue&quot;&gt;&lt;b&gt;+8n&lt;/font&gt;&lt;/b&gt;&lt;font color=&quot;green&quot;&gt;&lt;b&gt;-4p&lt;/font&gt;&lt;/b&gt;.

We can remove the &lt;font color=&quot;red&quot;&gt;&lt;b&gt;+&lt;/font&gt;&lt;/b&gt; in front:

&lt;font color=&quot;red&quot;&gt;&lt;b&gt;4m&lt;/font&gt;&lt;/b&gt;&lt;font color=&quot;blue&quot;&gt;&lt;b&gt;+8n&lt;/font&gt;&lt;/b&gt;&lt;font color=&quot;green&quot;&gt;&lt;b&gt;-4p&lt;/font&gt;&lt;/b&gt;

And we can get rid of the coloring:

&lt;b&gt;4m+8n-4p&lt;/b&gt;

That&#39;s it!  I&#39;ll bet you can now do such problem as this 
all in one step without coloring or putting &lt;b&gt;+&lt;/b&gt; signs or &lt;b&gt;1&lt;/b&gt;&#39;s
in front!

Edwin&lt;/pre&gt;&lt;/font&gt;
