three plus negative seven equals
 

00:00:54.690 --> 00:00:58.670 align:start position:0%
three plus negative seven equals
negative<00:00:54.930><c> four</c><00:00:55.940><c> let's</c><00:00:56.940><c> try</c><00:00:57.239><c> another</c><00:00:57.480><c> one</c><00:00:57.680><c> what</c>

00:00:58.670 --> 00:00:58.680 align:start position:0%
negative four let's try another one what
 

00:00:58.680 --> 00:01:01.330 align:start position:0%
negative four let's try another one what
about<00:00:58.949><c> negative</c><00:00:59.250><c> two</c><00:00:59.730><c> minus</c><00:01:00.149><c> negative</c><00:01:00.359><c> four</c>

00:01:01.330 --> 00:01:01.340 align:start position:0%
about negative two minus negative four
 

00:01:01.340 --> 00:01:04.340 align:start position:0%
about negative two minus negative four
our<00:01:02.340><c> first</c><00:01:02.730><c> number</c><00:01:02.910><c> is</c><00:01:03.180><c> negative</c><00:01:03.420><c> two</c><00:01:03.840><c> so</c>

00:01:04.340 --> 00:01:04.350 align:start position:0%
our first number is negative two so
 

00:01:04.350 --> 00:01:07.039 align:start position:0%
our first number is negative two so
that's<00:01:04.559><c> where</c><00:01:04.799><c> we'll</c><00:01:04.920><c> start</c><00:01:05.250><c> our</c><00:01:06.049><c> operation</c>

00:01:07.039 --> 00:01:07.049 align:start position:0%
that's where we'll start our operation
 

00:01:07.049 --> 00:01:09.200 align:start position:0%
that's where we'll start our operation
is<00:01:07.229><c> a</c><00:01:07.260><c> -</c><00:01:07.740><c> so</c><00:01:08.220><c> our</c><00:01:08.369><c> bird</c><00:01:08.580><c> will</c><00:01:08.760><c> look</c><00:01:08.939><c> left</c>

00:01:09.200 --> 00:01:09.210 align:start position:0%
is a - so our bird will look left
 

00:01:09.210 --> 00:01:12.410 align:start position:0%
is a - so our bird will look left
towards<00:01:09.840><c> the</c><00:01:09.990><c> negative</c><00:01:10.140><c> end</c><00:01:10.939><c> our</c><00:01:11.939><c> second</c>

00:01:12.410 --> 00:01:12.420 align:start position:0%
towards the negative end our second
 

00:01:12.420 --> 00:01:15.289 align:start position:0%
towards the negative end our second
number<00:01:12.540><c> is</c><00:01:12.840><c> a</c><00:01:12.900><c> negative</c><00:01:13.470><c> four</c><00:01:13.770><c> therefore</c><00:01:14.700><c> our</c>

00:01:15.289 --> 00:01:15.299 align:start position:0%
number is a negative four therefore our
 

00:01:15.299 --> 00:01:18.710 align:start position:0%
number is a negative four therefore our
bird<00:01:15.659><c> will</c><00:01:15.869><c> move</c><00:01:16.049><c> backwards</c><00:01:16.560><c> four</c><00:01:16.979><c> spaces</c><00:01:17.720><c> our</c>

00:01:18.710 --> 00:01:18.720 align:start position:0%
bird will move backwards four spaces our
 

00:01:18.720 --> 00:01:20.960 align:start position:0%
bird will move backwards four spaces our
bird<00:01:19.080><c> landed</c><00:01:19.500><c> at</c><00:01:19.590><c> positive</c><00:01:20.070><c> two</c><00:01:20.310><c> and</c><00:01:20.580><c> that's</c>

00:01:20.960 --> 00:01:20.970 align:start position:0%
bird landed at positive two and that's
 

00:01:20.970 --> 00:01:23.600 align:start position:0%
bird landed at positive two and that's
our<00:01:21.150><c> answer</c><00:01:21.530><c> negative</c><00:01:22.530><c> two</c><00:01:22.979><c> minus</c><00:01:23.400><c> negative</c>

00:01:23.600 --> 00:01:23.610 align:start position:0%
our answer negative two minus negative
 

00:01:23.610 --> 00:01:29.960 align:start position:0%
our answer negative two minus negative
four<00:01:24.270><c> equals</c><00:01:24.509><c> two</c><00:01:25.939><c> let's</c><00:01:26.939><c> recap</c><00:01:28.759><c> the</c><00:01:29.759><c> first</c>
