Question

1. Tính giá trị biểu thức

A, 3 242 + 2 326 + 192

B, 520 401 + 27 429 - 13 965

C, 13 228 - ( 28 073 - 16 785 ) 

D, 86 572 - ( 58 406 + 9 275 )

Answer 1

A. 3,242 + 2,326 + 192 = 5,760

B. 520,401 + 27,429 - 13,965 = 534,865

C. 13,228 - (28,073 - 16,785) = 2,940

D. 86,572 - (58,406 + 9,275) = 18,891

Answer 2

a: \(3242+2326+192\)

\(=3242+192+2326\)

\(=3434+2326=5760\)

b: \(520401+27429-13965\)

\(=\left(520401+27429\right)-13965\)

\(=547830-13965=533865\)

c: \(13228-\left(28073-16785\right)\)

\(=13228+16785-28073\)

\(=\left(13228+16785\right)-28073\)

\(=30013-28073=1940\)

d: \(86572-\left(58406+9275\right)\)

\(=86572-67681\)

=18891
