235x(30+5)=235x35=8225

****nha các bạn

235 x ( 30 + 5 ) = 235 x 35 = 8225

235 x (30 + 5 ) 

= 235 x 35 

= 8225 . 

        Tick mk nha ! Nguyễn Linh Đan

a) (–30) + (–5) = –(30 + 5) = –35.

b) (–7) + (–13) = – (7 + 13) = –20;

c) (–15) + (–235) = –(15 + 235) = –250.

235 × 46 + 30 ÷ 765 - 235 × 16
= 10810 + 2/51 - 3760
= 359552/51

Ai biết giúp tui sos

= 10810 + \(\dfrac{2}{51}\) - 3760

= \(\dfrac{359552}{51}\)

`235 xx 46 + 30 xx 765 - 235 xx 16`

`235xx46-235xx16+30xx765`

`235xx(46-16)+30xx765`

`235xx30+30xx765`

`30xx(235+765)`

`30xx100`

`3000

a) Tính:

235 × (30 + 5) = 235 × 30 + 235 × 5 = 7050 + 1175 = 8225

5327 × (80 + 6) = 5327 × 80 + 5327 × 6 = 426160 + 31962 = 458122

b) Tính theo mẫu

4367 × 31 = 4367 × (30 + 1) = 4367 × 30 + 4367 × 1 = 131010 + 4367 = 135377

a, -35

b, -20

c, -250

1.Tính 
a) ( - 30 ) + ( - 5 ) =-35
b) ( - 7 ) + ( - 13 ) =-20
c) ( -15 ) + ( 235)=220
d) 16 + ( - 6 ) =10
e) 14 + ( - 6 ) =8
f) ( - 8 ) + 12 =4

\(\left(\frac{4}{5}+\frac{1}{5}\right)-\left(\frac{123}{235}+\frac{112}{235}\right):\frac{1}{2}\)

\(=1-1:\frac{1}{2}=-1\)

=1-1:1/2
=1-2
=-1
