-11 To calculate this, begin at the left side, then work them in order. -2 -8 = -10 + 3 - 2 + 5 -7 -10 + 3 -2 + 5 -7 -10 + 1 + -2 -9 + -2 = -11
2( 3 + 7 ) + 2(3) + (2)(7) 2(10) + 2(3) + (2)(7) 20 + 6 + 14 = 40
5 + 2 + 3 + 7 + (21/7) = 20
7 = 2 + 2 + 3
7 - 3 + 2 = 2
2 + 3 - 4 + 7 = -6
A minus and a minus makes a plus A plus and a plus makes a plus A minus and a plus or plus and a minus makes a minus 7 - -2 is a minus and a minus Therefore the answer is 7 + 2 = 9
7
(7-3)^2 plus (7-1)^2 = 16+36
11 + 7 + 5 + 4 + 3 + 3 + 3 + 2 + 2 + 2 = ?First, group things in groups of tens (or twenties).(11 + 5 + 4) + (7 + 3) + (3 + 3 + 2 + 2) + 2 = ?20 + 10 + 10 + 2 = ?30 + 12 = ?42 = ?So your answer is 42.
7 - 3 + 2 = 6
3 + 3 - 7 + 2 - 1 + 109 = 109
