Responses
−16−(−4)−(−4)−(−4)−(−4)=0
negative 16 minus left parenthesis negative 4 right parenthesis minus left parenthesis negative 4 right parenthesis minus left parenthesis negative 4 right parenthesis minus left parenthesis negative 4 right parenthesis equals 0
16−4−4−4−4=16−4(4)=0
16 minus 4 minus 4 minus 4 minus 4 equals 16 minus 4 left parenthesis 4 right parenthesis equals 0
4+4+4+4=16
4 plus 4 plus 4 plus 4 equals 16
−4−4−4−4=−16
negative 4 minus 4 minus 4 minus 4 equals negative 16

What model can you use to represent 10÷0?(1 point)
Responses
0+0+0+0+0+0+0+0+0+0=0
0 plus 0 plus 0 plus 0 plus 0 plus 0 plus 0 plus 0 plus 0 plus 0 equals 0
0−0(10)=0
0 minus 0 left parenthesis 10 right parenthesis equals 0
10÷0 is undefined because you cannot divide by 0.
10 divided by 0 is undefined because you cannot divide by 0.
0+0=0
