90
Use BODMAS/BIDMAS/PEDMAS: 9 + 6(22 + 4) = 9 + 6(26) = 9 + 6 × 26 = 9 + 156 = 165
Applying the laws of BODMAS, 6 + (4 x 10) + 9 = 55
9 + 9 + 9 + 9 + 9 + 9 + 6 + 6 + 6 + 6 + 2 + 2 + 23 + 3 + 3 + 4 + 4 + 4 = 123
-42 + 37 - (6 x 9) + (7/4) = -57.25
Commutativity.
(6 x 9) + 6 + 9 = 69
21 times 9 plus 6 is equal to 195.
The additive property.
4 * (-4) + 9 = -7; so -7 is equivalent to 4 times -4 plus 9.
6 + 9 + 7 + 4 + 65432 = 65,458
The answer to the mathematical equation of 1 6/9 plus 4 7/9 is 58/9 or 6 4/9.
