These blocks total +4 Each blue block represents +1 +3 +2 These blocks total +5 (+2)+(+3)=+5 +1 +4 These blocks total +5 (+4)+(+1)=+5 +5 + 4 −1 −9 +1 +9 +5 + 3 −2 −8 +2 +8 These blocks total -4 Each red block represents -1 -3 -2 These blocks total -5 (-2)+(-3)=-5 -1 -4 These blocks total -5 (-4)+(-1)=-5 - −5 4 −1 −9 +9 +1 - −5 2 −3 −7 +3 +7 - −5 3 −2 −8 +2 +8 - −4 4 0 −8 +8 +4 - −4 2 −2 −6 +2 +6 +3 -3 When the amount of blue and red blocks are equal, the result is ZERO (+3)+(-3)=0 a c All answer choices equal zero except one. Which choice does NOT equal zero? d b a c All answer choices equal zero except one. Which choice does NOT equal zero? d b a c All answer choices equal zero except one. Which choice does NOT equal zero? d b If there are more blue (positive) blocks than red (negative) blocks, the result is POSITIVE -2 +3 These blocks total +1 (+3) + (-2) = +1 a c All answer choices equal +2 except one. Which choice does NOT equal +2? d b a c All answer choices equal +3 except one. Which choice does NOT equal +3? d b a c All answer choices equal +1 except one. Which choice does NOT equal +1? d b + −2 +2 −2 4 +6 -6 + −2 +3 −3 5 +7 -7 −3 + +8 −8 5 +2 -2 +3 -5 If there are more red (negative) blocks than blue (positive) blocks, the result is NEGATIVE. These blocks total -2 (-5) + (+3) = -2 a c All answer choices equal -3 except one. Which choice does NOT equal -3? d b a c All answer choices equal -2 except one. Which choice does NOT equal -2? d b a c All answer choices equal -1 except one. Which choice does NOT equal -1? d b + −5 −1 −9 4 +1 +9 + −5 −1 −3 2 -2 +3 + −5 −1 +1 1 -4 +4 + −5 −1 −9 4 +1 +9 finito |
