After the MCWC and JMCWC happen later this month, the next in-person competition will be the Global Mental Math Olympiad 2024 (GMMO). It is organized by LiveMCL, who also run the Mental Math World Cup (online) each Summer.
This year, the GMMO will take place in Dubai on 26–27 October 2024, and is open to participants aged 6+ in three categories:
- Challenger (ages 6–8) on October 27
- Master (ages 9–11) on October 26
- Grandmaster (ages 12+) on October 26
Unlike most competitions, the tasks in the GMMO are multiple-choice. The tasks are also simpler than in other international competitions, making it more accessible to younger mental calculators. Here are some typical questions fromthe standard challenge:
- 208 – 56 + 36
- 29 × 19
- 65% of 700
- Half of 4518
- HCF of 91 and 63
- LCM of 45 and 75
- Exact square root of 4356
- Exact cube root of 91125
- Remainder of 45/7
- Prime factors of 567
Participants will use LiveMCL’s app during the competition. This means that results and leaderboards can be shared immediately.
There will be four categories:
- Everyone does the Standard Mandatory Challenge with a variety of calculation formats
- Optional additions and subtractions sprint
- Optional multiplications sprint
- Zen Master Challenge (open to all ages)
To register, please read the information and follow the instructions on LiveMCL’s official website. Note: the cost for registering is USD $100, plus a small fee for each optional challenge. Their website also contains study materials for all task categories. Registered participants can use their app for practising. Good luck!
If you have any questions about GMMO 2024, please contact the organizers (see link above) and not me (Daniel Timms) because I’m not organizing the GMMO.
