Hence, the value of m is 3 .
Multiplication is a method of finding the product of two or more numbers.
According to the work shown in figure , Lena is trying to calculate 39 x 4 using the standard algorithm.
She has to choose the value of "m" which is 3 because when we multiply the digit 9 by 4 , we get 36 and we carry 3 and add it to the next product that is 3 x 4= 12 +3 (or m).
Hence the resultant is 156 and the value of m in figure will be 3.
