HEBRON (Ma’an) — A 14-year-old Palestinian girl won first place in an international competition for intelligence after solving 240 math problems in six minutes.

Dania Husni al-Jaabari from Hebron won first place in The Mental-Arithmetic International Competition in Singapore. Ahmad Ayman Nashwiyeh, 8, also from Hebron, came in second place as he solved 180 problems in six minutes.

Some 3,000 participants from more than 15 countries took part in the competition.

Dania and Ahmad joined a mental-arithmetic program in Hebron two years ago where students practiced using a two-hand abacus mental-arithmetic teaching system; the system depends on using the fingers of the left and right hands to compute simultaneously, creating stimulation in both the left and right sides of the brain.

The governor of Hebron, Kamel Hmeid, congratulated Palestinians and Dania al-Jaabari.
