One such strategy we use to understand addition or subtraction facts is the doubles strategy or fact.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">When we add two of the <strong>same<\/strong> number, we add using the \u201cdoubles fact\u201d.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">For example, 1 + 1 and 2 + 2 are both doubles facts.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">Look at the example below:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full eplus-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"620\" height=\"295\" src=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2022\/08\/Doubles-plus-1-1.png\" alt=\"Example of Doubles Plus\" class=\"wp-image-8656\" title=\"Example of Doubles Plus\" srcset=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2022\/08\/Doubles-plus-1-1.png 620w, https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2022\/08\/Doubles-plus-1-1-300x143.png 300w\" sizes=\"auto, (max-width: 620px) 100vw, 620px\" \/><\/figure>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">4 + 4 = 8&nbsp; is a doubles fact. Doubles fact can help us know other additional strategies like doubles plus one.&nbsp; This strategy is used in the addition of two consecutive numbers, like 2 + 3.
