a problem with some missing symbols and this problem wants
- 00:26
us to plug in the signs that'll make the equation
- 00:28
true because true equations are just so much truth here
- 00:33
Our options for both are plus times or divided by
- 00:37
okay so let's see what we've got here One thing
- 00:39
that should jump out at us is that the numbers
- 00:41
on the right side of the equation are well pretty
- 00:43
big If we multiply them together we're going to get
- 00:46
a seriously big number and usually with this type of
- 00:49
problem that isn't usually the case It doesn't mean it
- 00:51
can't be the case but in this instance it ain't
- 00:54
bloody likely though probably isn't division either because we get
- 00:58
a half and what can you multiply by Nine to
- 01:01
get a half Well not any sort of nice even
- 01:03
number So let's nix that possibility is well okay well
- 01:07
Then if you put a plus sign on the right
- 01:08
side we get eighteen plus thirty six is fifty For
- 01:12
what about that Now nine times something equals fifty four
- 01:17
and that checks out because four is evenly divisible by
- 01:19
nine So as it turns out nine goes into fit
- 01:22
for exactly six times So to what Four equal six
- 01:27
uh yeah plus and that works so we need to
- 01:31
plug in a plus sign on both sides of the
- 01:33
equation and boom we're done okay that's about all the
- 01:36
truthiness we can handle for one day Our compliments Who
