check your math on the -5
19,385
126
[]
student
oh...
19,385
127
[]
volunteer
3-7 isn't -5
19,385
128
[]
student
3-7
19,385
129
[]
student
oh -4
19,385
130
[]
student
I'msorry.
19,385
131
[]
volunteer
Good catch!
19,385
132
[]
student
I'm sorry*
19,385
133
[]
volunteer
No problem!
19,385
134
[]
volunteer
Alright, sorry I confused you at first
19,385
135
[]
volunteer
want to try another?
19,385
136
[]
student
No.. You didn't, I just didn't get it... I'm getting it now, thanks.
19,385
137
[]
student
Yes! That would be wonderful
19,385
138
[]
student
You can clear the board
19,385
139
[]
student
Then it would be easier to write...
19,385
140
[]
student
okay.
19,385
141
[]
volunteer
This one is trickier
19,385
142
[]
student
is that a c?
19,385
143
[]
volunteer
is which
19,385
144
[]
student
the one by 7 with the exponent of 4
19,385
145
[]
volunteer
meant to be y
19,385
146
[]
student
oh.
19,385
147
[]
student
thanks. :)
19,385
148
[]
volunteer
ofc
19,385
149
[]
student
okay
19,385
150
[]
volunteer
so how would you start
19,385
151
[]
student
7/56 = 8
19,385
152
[]
student
i mean 1/8
19,385
153
[]
volunteer
Perfect!
19,385
154
[]
volunteer
Not quite
19,385
155
[]
student
oh...
19,385
156
[]
volunteer
because just plain w
19,385
157
[]
volunteer
isn't w^0
19,385
158
[]
volunteer
it's actually w^1
19,385
159
[]
student
56 has a w^2
19,385
160
[]
volunteer
yeah
19,385
161
[]
student
oh...
19,385
162
[]
volunteer
but the top one one is w^1
19,385
163
[]
volunteer
so 1-2
19,385
164
[]
volunteer
does that make sense?
19,385
165
[]
student
Yes
19,385
166
[]
volunteer
nice
19,385
167
[]
student
okay... is it right?
19,385
168
[]
volunteer
it's close
19,385
169
[]
student
oh... okay.
19,385
170
[]
volunteer
but I made this one extra hard
19,385
171
[]
volunteer
and my handwriting on the board isn't great
19,385
172
[]
volunteer
so let's work through this one together
19,385
173
[]
volunteer
you got 1/8 right
19,385
174
[]
student
It;s all right, Mines sucks too... :)
19,385
175
[]
volunteer
then x^6 over x^3
19,385
176
[]
volunteer
x^3 you got
19,385
177
[]
volunteer
ok this one
19,385
178
[]
volunteer
w^1
19,385
179
[]
volunteer
over w^2
19,385
180
[]
volunteer
what should the subtraction be
19,385
181
[]
student
-w
19,385
182
[]
volunteer
-w?
19,385
183
[]
student
w^-1
19,385
184
[]
volunteer
there we go
19,385
185
[]
volunteer
good catch
19,385
186
[]
student
okay..
19,385
187
[]
volunteer
then y
19,385
188
[]
volunteer
y^4 over y^2
19,385
189
[]
volunteer
you got that right
19,385
190
[]
volunteer
but then
19,385
191
[]
volunteer
I threw in an extra sneaky x
19,385
192
[]
volunteer
x^4 on the bottom
19,385
193
[]
student
David i see it
19,385
194
[ { "pii_type": "PERSON", "surrogate": "David", "start": 0, "end": 5 } ]
volunteer
so we take our x^3
19,385
195
[]
volunteer
over x^4
19,385
196
[]
volunteer
and our x^3 turns into?
19,385
197
[]
student
0.5
19,385
198
[]
student
0.75
19,385
199
[]
volunteer
not quite
19,385
200
[]
volunteer
remember the subtraction
19,385
201
[]
student
which is 3.4
19,385
202
[]
student
3/4
19,385
203
[]
volunteer
3-4
19,385
204
[]
student
-1
19,385
205
[]
volunteer
not division
19,385
206
[]
volunteer
Yep!
19,385
207
[]
student
oh yeah... I forgot about that.. My bad..
19,385
208
[]
volunteer
all good!
19,385
209
[]
volunteer
and then we have z
19,385
210
[]
student
okay..
19,385
211
[]
volunteer
which is z^1
19,385
212
[]
student
Oh yeah,.. I forgot about z
19,385
213
[]
volunteer
and there's no z on the bottom
19,385
214
[]
volunteer
so 1-0
19,385
215
[]
volunteer
and we end up with this
19,385
216
[]
student
z^4
19,385
217
[]
volunteer
how'd you get that?
19,385
218
[]
student
4 stays by itself since it is not divided by anything.
19,385
219
[]
student
That's how i got it.
19,385
220
[]
volunteer
z doesn't have a 4
19,385
221
[]
volunteer
that's y
19,385
222
[]
student
Oh...right... Good catch,,
19,385
223
[]
volunteer
alright, i'll let you do this one on your own
19,385
224
[]
student
okay.
19,385
