Multiply 97 × 98 in 3 Steps

Experience the Nikhilam Sutra — the method that predates calculators by 1,500 years.

Step 1
Find the deficiency from 100
97 100 − 97 = 3
98 100 − 98 = 2
Step 2
Cross-subtract for the left part
97 − 2 = 95
Step 3
Multiply the deficiencies
3 × 2 = 06
Result 97 × 98 = 9506 Combine: 95 | 06

Standing on the Shoulders of Giants

GanitSūtram is built on 1,500 years of verified mathematical tradition — not myths, but documented science.

Āryabhaṭa (476 CE)

Pioneered the place-value system and zero, laying the structural foundation for all modern mathematics, trigonometry, and planetary astronomy.

ब्र

Brahmagupta (598 CE)

Authored the Brahmasphuṭasiddhānta, establishing the definitive mathematical rules for computing with zero and negative numbers.

भा

Bhāskara II (1114 CE)

Mastered advanced calculus concepts and algebraic equations in his seminal masterpiece Līlāvatī, centuries before their European formalization.

ती

Swami Bharati Krishna Tirtha (1884 CE)

Synthesized the 16 Vedic Sūtras into a unified, ultra-fast mental calculation engine, recovering the "Golden Thread" of computations from ancient texts.

What the Great Minds Said

"Mathematics is the queen of the sciences, and number theory is the queen of mathematics."

— Carl Friedrich Gauss

"Pure mathematics is, in its way, the poetry of logical ideas."

— Albert Einstein
