Vertically and Crosswise Multiplication Calculator

Explore the fascinating Vertically and Crosswise Multiplication Calculator, an online visual tool based on the famous Vedic Maths sutra “Urdhva Tiryagbhyam”, meaning “Vertically and Crosswise”. This ancient Indian method performs multiplication through a series of digit combinations, forming diagonal and vertical patterns that together produce the product — step by step.

Enter any multiplicand and multiplier up to 6 digits each, and watch how every step unfolds visually. The tool dynamically constructs tables showing which digits interact in each step, with arrows connecting them to illustrate the criss-cross structure of the calculation. Carry-overs from previous steps are clearly shown, helping learners understand the logic behind this right-to-left multiplication approach.

Each multiplication follows an odd number of steps, determined by the rule:

No. of Steps  2  (no. of digits in the longer number)  1

This makes it an excellent interactive way to grasp how the Criss-cross (Vertically and Crosswise) method scales elegantly for numbers of any length.
