We start by working out the expressions inside the brackets,
:<math>3-\bbox[#FFEEAA;,1.5pt]{\,(7-4)\,}+\bbox[#FFEEAA;,1.5pt]{\,(6-5)\,} = 3-\bbox[#FFEEAA;,1.5pt]{\,3\,}+\bbox[#FFEEAA;,1.5pt]{\,1\,}</math>.
:<math>3-\bbox[#FFEEAA;,1.5pt]{\,(7-4)\,}+\bbox[#FFEEAA;,1.5pt]{\,(6-5)\,} = 3-\bbox[#FFEEAA;,1.5pt]{\,3\,}+\bbox[#FFEEAA;,1.5pt]{\,1\,}</math>.

Then, all we have to do is to combine the numbers

We start by working out the expressions inside the brackets,

3−(7−4)+(6−5)=3−3+1.

Then, all we have to do is to combine the numbers

=3−3+1
=0+1
=1.
