understand the sum you need to achieve.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Example<\/strong>: The target sum is 50.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-normal-font-size\"><strong>List Possible Numbers<\/strong>:<\/p>\n\n\n\n<p class=\"has-normal-font-size\">Think of numbers that could potentially add up to the target sum.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Example<\/strong>: For a sum of 50, possible numbers could be 20, 30, 25, etc.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-normal-font-size\"><strong>Test Combinations<\/strong>:<\/p>\n\n\n\n<p class=\"has-normal-font-size\">Add different combinations of the numbers to see if they meet the target sum.<\/p>\n\n\n\n<p class=\"has-normal-font-size\"><strong>Example<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>20 + 30 = 50 (Correct combination)<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>25 +

may be more than one combination that adds up to the target sum.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Example<\/strong>: For a sum of 40, combinations could include 10 + 30, 20 + 20, 15 + 25, etc.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-normal-font-size\"><strong>Verify the Solution<\/strong>:<\/p>\n\n\n\n<p class=\"has-normal-font-size\">After selecting numbers, double-check the addition to ensure it equals the target sum.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Example<\/strong>: Verify 20 + 30 = 50 by adding the numbers again.<\/li>\n<\/ul>\n\n\n\n<figure
