Question

52 x 2 x 431 =
509 x 135 =
125 x 435 =
12. Calculează, ținând cont de ordinea operațiilor:
527 x 35 + 16 x 25 - 13 x 14 x 27 =
432 x 59 - 24 x 36 + 23 x (248 - 12 x 12) =
36 x 27 + 507 x 25 – 12 x 13 x 27 =
bo
35 x 324 + 15 x (13 x 13 - 12 X 12) – 2Y (220

Answer 1

Răspuns:

52•2•431=44.824

509•135=68.715

125•435=54.375

527•35+16•25-13•14•27=

=18.445+400-182•27

=18.445+400-4.914

=13.931

432•59-24•36+23•(248-12•12)=

=432•59-24•36+23•(248-144)

=432•59-24•36+23•104

=25.488-864+2.392

=27.016

36•27+507•25-12•13•27=

=972+12.675-156•27

=972+12.675-4.212

=9.435

35•324+15•(13•13-12•12)-2Y•220=

=35•324+15•(169-144)- 2Y•220

=35•324+15•25-2Y•220

=11.340+375-440Y

=11.275Y
