Chỉ cần ghi lời kết quả
(123 .7 + 123 .3) . (98 . 198 + 98 .2 ) .1000 : ( 98 - 49 . 2)
98+23+19+36+45+123+98+72=mấy

123 - 98
= (123 - 2) - (98 + 2)
= 121 - 100
= 21
x + 98 = 123
x - 21 = 87
x + 98 = 123
x = 123 - 98
x = 25
~~~~~~~~~~~~~~~~
x - 21 = 87
x = 87 + 21
x = 108
x + 98 = 123
x = 123 - 98
x = 25
x - 21 = 87
x = 87 + 21
x = 108
24 x 32 - 43 + 58 x 78 - 98 x 123 = ?
24 x 32 - 43 + 58 x 78 - 98 x 123
= 768 - 43 + 4524 - 12054
= - 6805
24 x 32 - 43 + 58 x 78 - 98 x 123

tính :
[ 1278 + 789123 ] -1567 + [123 : 3 +98]
[ 1278 + 789123 ] - 1567 + ( 123 : 3 + 98 )
= 790401 - 1567 + ( 41 + 98 )
= 788834 + 139
= 788974
[1278+789123]-1567+[123:3+98]
= 790401-1567+(41+98)
=488834+139
=488973
[ 1278 + 789123 ] -1567 + [123 : 3 +98]
= 790401 - 1567 + (41 + 98)
