Va rog repede este urgent​

Răspuns :

Explicație pas cu pas:

a)500-7×15-144= 500-105-144= 251

b) (2400+3700) - 1420= 6100-1420=4680

c) [25x (9×10-9)]-110= (25×81)-110= 2025-110=1915

d) 300+ (625-158)= 767

e) 1000-0= 1000

Răspuns:

a)500 - 63: 9 x 15 - 12 x 12 =

500-7×15-114=

500-105-114=

395-114=281

b)(240 x 10+ 370 x 10) - 355 x 4 =

(2400+3700)-1420=

6100-1420=4680

c) [25 x (81:9 x 10 - 72:8)]- 110 =

[25×(9×10-9)]-110=

(25×81)-110=

2025-110=1915

d)300 + [(125 x 5 - (18 x 9 - 32:8)] =

300+[(625-(162-4)]=

300+(625-158)=

300+467=767

e) 1 000 - [(27 x 7 + 35 x 8) x 0] =1000
