Example 2: subtraction in expanded method in
words.
486 – 263 by arranging the numbers in expanded
form in words.
486 = 4 hundreds + 8 tens + 6 ones
-263 = - 2 hundreds + 6 tens + 3 ones
= 2 hundreds + 2 tens + 3 ones
= 223
Steps to understand better:
(i) Subtracting one’s column = 6 ones - 3 ones = 3 ones
(ii) Subtracting tens column = 8 tens - 6 tens = 2 tens
(iii) Subtracting hundreds column = 4 hundreds - 2
hundreds = 2 hundreds
(iv) 2 hundreds + 2 tens + 3 ones = 223
