Maths Whizz

Today I learned my adding and borrowing from big numbers.If the equation was 23 - 14.First,I do 3 - 4,but I can't minus 4 from 3.I borrow 1 from the 2 and it makes the 3 to 13 and makes the 2 to 1.So I minus 4 from 13 which equals 9 and 1 - 1 = 2 and the answer is 29.I had fun on Maths Whizz today.I hope you use this method on your maths work.
