Step-by-step explanation: Using GEMDAS method
1. (6+4) ÷ 2=
10 ÷ 2= 5
2. 12- (2 x 2) + 10=
12-4 + 10=
12+ 6 = 18
3.(2+3-2) x 8 ÷ 3=
3 x 8 ÷ 3=
24 ÷ 3= 8
4. (720 ÷ 90) x (180 ÷ 90) =
8 x 2 = 16
5. (6^2 -2) ÷ 2+54=
34 ÷ 2 + 54=
17+54= 71
6. [36-(12+2)]-3 x 2= The bracket will become parenthesis
(36-14)-3 x 2=
22-3 x 2=
22 -6= 16
7. [ 66 ÷ 6-(2+2^5)+99]=
(66 ÷ 6-34+99)=
11-34+99=
11-133= 122
8. [11+35+(8+2) x 4^4]=
(11+35+10 x 4^4) =
11+35+10 x 256=
11+ 35 + 2560= 2606
9. (12 ÷ 2)^3 x (3+9) + (6+4)-3^2=
6^3 x 12+ 10-3^2=
216+12+10-9=
238-9= 229
10. {[(32+65-29) x 3] -10}^2=
{[(97-29) x 3] -10}^2=
[(68 x 3) -10]^2=
(204-10)^2=
(194)^2= 37, 636
