+<p>
+ this activity is related on how we can multiply two numbers and check if the product found is correct or not.we use proof.
+</p>
+<h4>
+ by making a proof we use the chart :
+ <span class="multilang" style="font-weight: normal;" lang="am">
+  x
+ </span>
+</h4>
+<p>
+ <br />
+ <span style="text-decoration: underline; font-weight: bold;">
+  Examples
+ </span>
+ :here we have some calculation on multiplication and we shall check if the product found is correct or not.
+ <br />
+ 1) 234

+ here are some rules to follow when making a proof of seeing if the product found are correct or not.
+ <br />
+ <br />
+ <span style="font-weight: bold; text-decoration: underline;">
+  Rules:
+ </span>
+ <br />
+ a.Add the digits in multicand until you get a single digit and fill in the chart
+ <br />
+ <br />
+ b.Add the digits of the multiplier until you get a single digit and fill in the chart.
+ <br />
+ <br />
+ c.Multiply the two answers obtained
+ <br />
+ <br />
+ d.Add the digit of the product
+ <br />
+ <br />
+ e.Add the digits of the answers if it is a single digit.
+ <br />

+<p>
+ <span style="text-decoration: underline; font-style: italic;">
+  Application of the above rules in the above examples
+ </span>
+ <span style="font-style: italic;">
+ </span>
+</p>
+<p>
+ here is an image of like
+ <span style="font-weight: bold;">
+  x in which
+ </span>
+ numbers are in the intersection of 2 lines.we are going to apply the above rules by checking if the product found on the above examples are correct or not.
+</p>
+<p>
+ 1)a)2+3+4=9
+</p>
+<p>
+ b)1+3=4
+</p>
+<p>
+ c)9x3=27=2+7=9
+</p>
+<p>
+ d)2+8+0+8=18=1+8=9
+</p>
+<p>
+ if the numbers found on rules c and d are equal the product is correct else it's incorrect.For our first example the product is correct because number found on rule c and d are the same.
+</p>
+<p>
+ 2)a)2+3+7+5=17=1+7=8
+</p>
+<p>
+ b)1+2+5=8
+</p>
+<p>
+ c)8x8=64=6+4=10=1+0=1
+</p>
+<p>
+ d)2+9+6+8+7+5=37=3+7=10=1+0=1
+</p>
+<p>
+ As the number found in rule c and d are the same,our product is correct.
