------------------------------Instructions--------------------------- Click on the icons input numbers answer ------------------------------ADDITION---------------------------- if you don't know how to add, count up X amout of times from Y (1 2, 3, 4, 5, 6, 7 Y X X X X X X) ---------------------------SUBTRACTION---------------------- same as addition, but backwards Y number of times from X (7 6, 5, 4, 3, 2, 1 Y X X X X X X) --------------------------MULTIPLICATION---------------------- Idk how to explain this, 4 times 7 = (1 2 3 4 5 6 7 4 + 4 + 4 + 4 + 4 + 4 + 4 = 28) ------------------------------DIVISION-------------------------- minus X from Y and result, 8 divide by 4 = 2 (8 - 4 = 4) 1 (4 - 4 = 0) 2 another example: 14 divide by 3 = 4 and 2/4 (aka 1/2 or half) (14 - 3 = 11) 1 (11 - 3 = 8) 2 (8 - 3 = 5) 3 (5 - 3 = 2) 4 (can't minus 3 from 2, so it becomes fraction)
Calculators (P.S. the explanations took too long to make) comment if you want more explanations (about math)
