The counting issue! I must admit that, though this does not work in English, it is helping me to remember the Indonesian construction!
But the English needs to be "how many fingers do you have."
But do we have 8 or 10 - is a thumb considered a finger in Indonesian?
Why everywhere else is the literal translation given (here this would be) -- your fingers are how many? But here it is the correct English phrase. Use BOTH for consistency across lessons!
