Question

Calculează în două moduri (12+8):2 (16+4):4 (24 +4):2 (23+13):6. (40-6):6. (32+24):8. (15+25+10):5. (20-18+14):2. (46-4):7. (16-4):2​

Answer 1

Răspuns:

(12+8):2= 20 : 2= 10   sau 12 :2+ 8:2=6+4=10

(16+4):4= 20: 4=5    sau 16:4+ 4:4= 4+1= 5

(24 +4):2 =28:2  =14 sau 24:2+ 4:2= 12+2= 14

(23+13):6=36 :6=6   sau 24:6+12:6= 4+2= 6

(40-6):6=36:6=6      

(32+24):8=56:8=7 sau    32:8+ 24:8= 4+3= 7

(15+25+10):5=50:5=10    sau 15:5+ 25:5+ 10:5= 3+5+2=10

(20-18+14):2=16: 2=8    sau 20:2- 18:2 + 14:2= 10 -9 +7= 1+7=8

(46-4):7=42 :7=6    

(16-4):2=​12:2= 6      sau 16:2 - 4:2= 8- 2= 6
