I have a project to hand in and the topic is Limitations of vedic math.
what type of math sums can it not solve? Do people disagree with some of the methods in vedic math?

Limitations of Vedic Math Part 1

Vedic mathematics principles have limitations. The applicability has to be further tested before actual use of the principle and the bounds of its applicability. However in squaring two digit numbers ending with 5. the principle can be used. For example consider a number n 5, where n can take values between 0 and 9 and including them, then

n5 x n5 = n(n+10)25
Because 10 = 1 mod 9, this becomes
n5 x n5 = n(n+1)25
Put any value for n, between 0 and 9. This will work.
If n = 7, 752 = (7 x 8)25 = 5625

Advent ages

Vedic Math is simpler yet more interesting than regular Math.
Vedic Mathematics enriches knowledge and understanding of Mathematics, which shows clear links and continuity between different branches of Mathematics.
Vedic Mathematics methods come as a boon for all competitive exams (such as Management, Banking, Engineering etc.) as mathematic problems can be solved with amazing accuracy and speed.
Vedic Mathematics being a most natural way of working can be learnt and mastered with ease and in a very short time.
Vedic Mathematics system also provides a set of independent crosschecking methods.
The element of choice and flexibility develops clarity of mind and intuition.
Leads to improvement in mental ability, sharpness, creativity and intelligence.
Problems are reduced to one-line answers.
Reduces dependence on calculators.
Vedic Math is complementary to regular Math taught in schools.
Students learning Vedic Math excel at school.
