1) 2^2 - 7 q^5 + 6 - 3^3
= 4 - 7q^5 +6 - 27
= 10 -27 -7q^5
= -17 -7 q^5
2) 1+ 2 (-1) /2 * 4- 5^2
= 1+( -2 / 2*4 ) -25
= 1 + ( -2 / 8) -25
= 1 - 1 /4 -25
= 4 -1 - 100 / 4
= -97 /4
= 4 - 7q^5 +6 - 27
= 10 -27 -7q^5
= -17 -7 q^5
2) 1+ 2 (-1) /2 * 4- 5^2
= 1+( -2 / 2*4 ) -25
= 1 + ( -2 / 8) -25
= 1 - 1 /4 -25
= 4 -1 - 100 / 4
= -97 /4
