+	<title>Basic Equations</title>
+    
+    <p>
+    Equations are entered in standard mathematical form.
+    For example to add 7 and 2 enter the following:
+    </p>
+    <example>
+    <p>
+    7+2
+    </p>
+    </example>
+    <p>
+    To solve, press the <gui>=</gui> button with your mouse or the <key>Enter</key> key on your keyboard.
+    </p>
+    <p>
+    Calculations are performed in mathematical order - multiplication and division are performed before addition and subtraction.
+    The following equation solves to 1 (3×2 = 6, 7−6 = 1).
+    </p>
+    <example>
+    <p>
+    7−3×2
+    </p>
+    </example>
+    <p>
+    To change the order of calculation use parenthesis.
+    The following equation solves to 8 (7−3 = 4, 4×2 = 8).
+    </p>
+    <example>
+    <p>
+    (7−3)×2
+    </p>
