that each place (units, tens, hundreds) must be correctly filled to make the addition accurate.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Example<\/strong>: If the sum is 800, you need to ensure that the digits you fill in result in 800 when added.<\/li>\n<\/ul>\n\n\n\n<p><strong>Work from Right to Left<\/strong>:<\/p>\n\n\n\n<p>Start with the rightmost column and use the known digits to find the missing ones.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Example<\/strong>: If the units column is _+7=0 (or 10), you need to find that the missing digit is 3 (since 7 + 3 = 10).<\/li>\n<\/ul>\n\n\n\n<p><strong>Carry Over if Needed<\/strong>:<\/p>\n\n\n\n<p>If the sum of a column is 10 or more, carry over the tens to the next column.<\/p>\n\n\n\n<ul
