x = 200
Tính nhẩm:
a) 810 + 50 = ......
350 + 250 = ......
550 - 500 = ......
b) 600 + 60 = ......
105 + 15 = ......
245 - 45 = ......
c) 200 - 100 = ......
250 - 50 = ......
333 - 222 = ......
a) 810 + 50 = 860
350 + 250 = 600
550 - 500 = 50
b) 600 + 60 = 660
105 + 15 = 120
245 - 45 = 200
c) 200 - 100 = 100
250 - 50 = 200
333 - 222 = 111
x - 200 = 600 + 200
x - 200 = 600 + 200
x - 200 = 800
x = 800 + 200
x = 1000
Vậy x = 1000
x - 200 = 600 + 200
x - 200 = 800
x = 800 + 200
x = 1000
x + 200 = 600 + 200
x + 200 = 600 + 200
x + 200 = 800
x = 800 - 200
x = 600
