The associative property lets you regroup this as
(150 + 850) + 889
Using mental math, you immediately recognize that 150+850 = 1000. Now you understand you have
1000 + 889, which is much easier to add.
1000 + 889 = 1889
(150 + 850) + 889
Using mental math, you immediately recognize that 150+850 = 1000. Now you understand you have
1000 + 889, which is much easier to add.
1000 + 889 = 1889
