Here are some tips to save time in your extreme additions: Tip 1 The result of adding a two-digit number with 9 is quickly obtained from this number as follows: - The number of units minus 1. - The tens digit plus 1. Examples: (25 + 9) = 34 (46 + 9) = 55 (78 + 9) = 87 Tip 2 The result of the extreme addition of 9 with any number from 1 to 9 equals that number. Examples: (4 + 9) => 4 because (4 + 9) = 13 and (1 + 3) = 4 (2 + 9) => 2 because (2 + 9) = 11 and (1 + 1) = 2 (7 + 9) => 7 because (7 + 9) = 16 and (1 + 6) = 7 (9 + 9) => 9 because (9 + 9) = 19 and (1 + 8) = 9 Tip 3 It is faster to add 245 + 637 to the extreme by doing 2 + 4 + 5 + 6 + 3 + 7. Tip 4 Try to get a maximum of 9 in the longest additions, in order to apply tip # 2. Here are all the additions to get the number 9: 1 + 8 = 9 2 + 7 = 9 3 + 6 = 9 4 + 5 = 9 Tip 5 Learn by heart your addition tables, so you no longer have to rely on your fingers to find the result! Lol. 7 + 5 = 12 8 + 4 = 12 6 + 7 = 13 8 + 5 = 13 8 + 6 = 14 7 + 8 = 15 etc ... Be positive, combative, don't give up after a single game, have fun and progress.
