123 + 123 = ?
234 + 123 ........ 234 + 123
123 + 123= 246
234 + 123 = 234 + 123
123+123*234+234*345+345*456+456*567+567*678+678*789+789
234 + 234 - 123=^^^^^^^^
\(234+\left(234-123\right)\)
\(=234+111\)
\(=345\)

k nhé chúc học tốt
Tính hợp lí:
a) \(A=\left(\frac{3}{4}-\frac{4}{7}-\frac{5}{6}\right):\left(-\frac{3}{10}+\frac{4}{14}-\frac{-5}{12}\right)\left(\frac{1}{12}-\frac{7}{6}\right)\)
b) 123.(-234+4356-2312)+234.(123-2312)-2312.(-234-123)
a: \(A=\dfrac{63-48-70}{84}:\dfrac{-3\cdot84+4\cdot60+5\cdot70}{840}\cdot\dfrac{1-14}{12}\)
\(=\dfrac{-55}{84}\cdot\dfrac{840}{338}\cdot\dfrac{-13}{12}=\dfrac{55}{1}\cdot\dfrac{10}{338}\cdot\dfrac{13}{12}=\dfrac{275}{156}\)
b: \(=-234\cdot123+123\cdot4356-123\cdot2312+234\cdot123-234\cdot2312+2312\cdot234+2312\cdot123\)
\(=123\cdot4356-123\cdot2312+123\cdot2312=123\cdot4356=535788\)
a)321+456-234=?
b)543-123+456=?
c)234+234-321=?
321 + 456 - 234 = 543
543 - 123 + 456 = 876
234 + 234 - 321 = 147
a) a)321+456-234= 543
b)543-123+456=876

123 + 234 = ?
123 x 34 = ?
123 : 3 = ?

Trả lời
123 + 234 = 357
123 x 34 = 4182
123 : 3 = 41
1235 - 876 = 359
~ Hok Tốt ~
= 357
= 4182

Họk tốt nha !
mk nhé
