Hi Dennis,
The Bridge & Vitruvian Man methods are the identical in the steps. Only the visualization is different. You will see that with these two methods you will calculate faster than the LR method for 2 and 3 digit multipliers like 123 x 23 or 123 x 567 (23 being a 2 digit multiplier and 123 being a 3 digit multiplier).
Once you master them you can go on to UT method. UT Method shines for 5+ digit multiplicands. Like 542351 x 23.
The logical progression is to start with the LR method and proceed with the Bridge/Vitruvian Man Method and then finish off with UT method.
Let me know if this answer helped. Please do leave a review if you enjoyed the course as it really helps reach more students. You can post what you posted here. 🙂
