Seven groups waited in line to see a concert. there were 9 people in each group. how many people were there in total?
9x7= 63
1.) 3 + 2 x 10 = 3 + 20 = 23
2.) 2(1-4)^2 = 2(-3^2) = 2(9) = 18
3.) -3^2 + 3^2 = 9 + 9 = 18
4.) 8 - [(4-7) + (8-1)] = 8 - [-3 + 7] = 8 - 4 = 4
5.) 4 - {8 - (2-4)} = 4 - {8 - (-2)} = 4 - {8 + 2} = 4 - 10 = -6
