Question

efectuati calculele 879+363:11-25x36, 16x16-975:75-9X27, 15x18-490:70-261 ,56X72:126+222-88

Answer 1

1) 879+363:11-25×36=12
879+33-900=12
912-900=12
2) 16×16-975:75-9×27=1
256-13-243=1
3) 15×18-490:70-261=2
270-7-261=2
4) 56×72:126+222-88=166
4032:126+222-88=166
32+222-88=166
254-88=166

Answer 2

1.363:11=33+879=912

2.16X16=256-(975:75=13)-(9x27=243)=256-13-243=0

3.15x18=270-(490:70=7)-261=270=7=261=2

4.52x72=3744:(126+222-88=260)=3744:260=14.4
