Answer 1

72:8+9×9=88  F
9+81=88
90≠88

100-5×7-42:7=5×10+9 A
100-35-6=50+9
 65-6=59
 59=59

 6×7+72:9=(16+26):7+44 A
 42+8=42÷7+44
 50=6+44
 50=50 

Answer 2

72 :8+9•9=88 (fals) trebuia sa fie asa
72:8+9•9=9+9•9=9+81=90

100-5•7-42:7=5•10+9
100-35-6=50+9
100-29-6=59
71-6=59
59=59 adevarata

6•7+72:9=(16+26):7+44
42+8=42:7+44
42+8=6+44
50=50 este adevarata
