Fascinating Fact:
The International Space Station travels at about 27,700 km/h, roughly nineteen times faster than a passenger jet at about 1,450 km/h.
In KS3 Maths, the 19 times table is a great workout for mental methods. Use round-and-adjust strategies (20n − n), break 19 into 10 and 9, and apply nineteen facts in measurement, ratio, and scale drawings.
Key Terms
- Multiple of 19: Any number in the 19 times table (19, 38, 57, 76, …).
- Prime number: A number with exactly two factors, 1 and itself. Nineteen is prime.

Frequently Asked Questions (Click to see answers)
What is an easy way to calculate 19 times a number?
Use round and adjust: 19 × n = (20 × n) − n. Another option is 19 × n = (10 × n) + (9 × n). Pick the one you can do fastest.
How can I check if a number is a multiple of 19?
Divide the number by 19. If the result is a whole number with no remainder, it is a multiple of 19. For estimation, compare with nearby 190s or 1,900s.
Where do we use the 19 times table in real life?
Speed comparisons (like ISS vs jets), stock counted in 19s, grid layouts with 19 columns, and prime-based code puzzles often use nineteen facts for quick scaling.
