I know you folks like a challenge, but this is one my daughter asked me yesterday - her maths teacher had set it and we're stuck

Make the numbers 1 to 20 using four lots of 4 (so 4, 4, 4, 4) in any combination, and any mathematical symbol. S you can use 44, 4 to the power of 4, and so on.

for example

to make 6 we have ((4 + 4) / 4) + 4 = 6

to make 15 we have (44 / 4) + 4 = 15

to make 10 we have (44 - 4) /4 = 10

and so on.

But we're stuck on 19

Any ideas.
