[]
student
I can raise it for you quickly
16,143
429
[]
volunteer
OK. Thank you
16,143
430
[]
student
You're welcome
16,143
431
[]
student
Here we go.
16,143
432
[]
volunteer
All right. The next one, G of X minus F of X.
16,143
433
[]
volunteer
It a similar idea
16,143
434
[]
volunteer
Yeah.
16,143
435
[]
volunteer
except
16,143
436
[]
student
It's nicked
16,143
437
[]
volunteer
you put GovX at the top.
16,143
438
[]
volunteer
and then Liam at the bottom.
16,143
439
[ { "pii_type": "PERSON", "surrogate": "Liam", "start": 9, "end": 13 } ]
volunteer
And you're not adding them
16,143
440
[]
volunteer
you're subtracting them
16,143
441
[]
student
Mm
16,143
442
[]
student
So
16,143
443
[]
student
5 eggs.
16,143
444
[]
student
1/3
16,143
445
[]
student
plus
16,143
446
[]
student
4
16,143
447
[]
student
OK, now we do big minus.
16,143
448
[]
student
and then FS
16,143
449
[]
student
negative
16,143
450
[]
student
3 X
16,143
451
[]
student
uh
16,143
452
[]
volunteer
Mhm.
16,143
453
[]
student
so positive for minus 4, so that costs out like that's it.
16,143
454
[]
volunteer
Yeah
16,143
455
[]
student
Um
16,143
456
[]
student
5
16,143
457
[]
student
5 X
16,143
458
[]
student
minus 3. Wait.
16,143
459
[]
volunteer
Mhm.
16,143
460
[]
student
How could we wait 5 minus -3, that'll be 8.
16,143
461
[]
student
8.
16,143
462
[]
volunteer
Yeah, exactly
16,143
463
[]
student
P X
16,143
464
[]
volunteer
Mhm
16,143
465
[]
volunteer
Yes
16,143
466
[]
student
No, that's all that's the answer.
16,143
467
[]
volunteer
Yeah
16,143
468
[]
student
Mhm
16,143
469
[]
student
It's uh same goes the other one, but
16,143
470
[]
volunteer
Mhm
16,143
471
[]
student
it's a
16,143
472
[]
student
FN X and then subtraction.
16,143
473
[]
volunteer
Yeah
16,143
474
[]
student
Oh, that's pretty simple
16,143
475
[]
volunteer
So it's, yeah. It's uh, for the first one, it doesn't matter which one is on top or bottom.
16,143
476
[]
volunteer
cause you're just adding them
16,143
477
[]
student
Mhm
16,143
478
[]
volunteer
But when you're subtracting, these are two different. If you do this one, you'll get a different answer.
16,143
479
[]
student
OK.
16,143
480
[]
volunteer
It's not a
16,143
481
[]
volunteer
what's the word, communicative.
16,143
482
[]
student
Oh
16,143
483
[]
student
oh
16,143
484
[]
student
I got it
16,143
485
[]
student
OK.
16,143
486
[]
volunteer
That that's probably more information. You don't need to know.
16,143
487
[]
volunteer
All right.
16,143
488
[]
student
OK
16,143
489
[]
student
so I'll do
16,143
490
[]
student
negative
16,143
491
[]
student
3X
16,143
492
[]
student
The see here.
16,143
493
[]
student
Well, for Liam.
16,143
494
[ { "pii_type": "PERSON", "surrogate": "Liam", "start": 10, "end": 14 } ]
student
OK
16,143
495
[]
student
4.
16,143
496
[]
student
So, so that'll be boom sub -3 minus
16,143
497
[]
student
3W9 negative, and then that'll be 8 X.
16,143
498
[]
student
1/3
16,143
499
[]
volunteer
Mhm
16,143
500
[]
student
That's
16,143
501
[]
volunteer
Yup.
16,143
502
[]
volunteer
Yeah
16,143
503
[]
student
So I think I uh I think I've got the concept of it.
16,143
504
[]
volunteer
Yeah. So it's just, this is for addition and subtraction. These are different rules.
16,143
505
[]
volunteer
when you start talking about
16,143
506
[]
volunteer
multiplication or division, but
16,143
507
[]
volunteer
that's not on the your assignment, so
16,143
508
[]
volunteer
you'll learn about that later
16,143
509
[]
student
Mhm
16,143
510
[]
student
And what if it's like this, Liam
16,143
511
[ { "pii_type": "PERSON", "surrogate": "Liam", "start": 28, "end": 32 } ]
volunteer
Mhm.
16,143
512
[]
student
Let me delete this all.
16,143
513
[]
student
um
16,143
514
[]
student
it's goes like FG
16,143
515
[]
student
boom, she
16,143
516
[]
student
Well if it's like this
16,143
517
[]
student
So how do I plug it in?
16,143
518
[]
volunteer
OK, so
16,143
519
[]
volunteer
this is kind of like what we did.
16,143
520
[]
volunteer
the previous problem
16,143
521
[]
volunteer
but it's a little more involved. So it's the same idea. It's not a number
16,143
522
[]
volunteer
we're not evaluating it. So if, if they ask you to fill out a table
16,143
523
[]
volunteer
that's how you would do it. You would do GFX first, and then
16,143
524
[]
volunteer
do F of
16,143
525
[]
volunteer
GFX, right?
16,143
526
[]
volunteer
So this is
16,143
527
