A student of class V performed multiplication of two digit numbers in the following way :
17 x 26 = 17 x (20+ 6) = 340 + 102 = 442
How should the teacher evaluate this student ?

Correct option is B

he student has correctly calculated the product of 17 and 26. The student has used a different method than the one taught in class, but the method is correct and demonstrates a good understanding of place value and multiplication. The teacher should praise the student for their creativity and problem-solving skills, and should also explain the standard method of multiplication so that the student can understand both methods.
