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
