		<h1>Doing sums</h1>
		<p>The command <code class="command">PRINT</code>, followed by a sum, tells the computer to work out the sum and put the answer on
			the screen. Try the <code class="command">PRINT</code> commands shown below. The commands have no line
			numbers, so the computer carries out each one straight away.</p>
<pre>
PRINT 2+2
PRINT 2*3
PRINT 6/2
</pre>

		<h2>Hours program</h2>
		<p>This program makes the computer
			work out the number of hours in a year.
			Line 30 does the calculation. It multiplies the number of days in a year, by the number of hours in a day.</p>
		<p>Let’s type it in and <code class="command">RUN</code> it now.</p>
<pre>
10 CLS
20 PRINT "THERE ARE "
30 PRINT 365*24
40 PRINT "HOURS IN"
50 PRINT " A YEAR"</pre>
