Lionel Vintage Postwar No. 2018 Prairie-type 2-6-4 Steam Locomotive. For sale is a Lionel vintage postwar No. 2018 Prairie-type 2-6-4 steam locomotive that can be dated to 1956-1959, which has been fully restored and is now in excellent condition. The entire engine—including the motor, e-unit, smoke unit, drive hardware, roller pickups, and trucks—was disassembled, thoroughly but. This was an open-label, parallel-group, phase 3b trial done at 194 hospitals, clinical institutions or private practices in 16 countries. Eligible patients were aged 18 years or older and had type 2 diabetes with HbA 1c 70–105% (530–910 mmol/mol) on metformin monotherapy.
Wow! What a mouthful of words! But the ideas are simple.
Commutative Laws
The 'Commutative Laws' say we can swap numbers over and still get the same answer ...
... when we add:
Example:
... or when we multiply:
a × b = b × a
Example:
Commutative Percentages!
Because a × b = b × a it is also true that a% of b = b% of a
Why 'commutative' ... ?
Because the numbers can travel back and forth like a commuter.
Associative Laws
The 'Associative Laws' say that it doesn't matter how we group the numbers (i.e. which we calculate first) ...
... when we add:
... or when we multiply:
(a × b) × c = a × (b × c)
Examples:
| This: | (2 + 4) + 5 = 6 + 5 = 11 |
| Has the same answer as this: | 2 + (4 + 5) = 2 + 9 = 11 |
| This: | (3 × 4) × 5 = 12 × 5 = 60 |
| Has the same answer as this: | 3 × (4 × 5) = 3 × 20 = 60 |
Uses:
Sometimes it is easier to add or multiply in a different order:
What is 19 + 36 + 4?
19 + 36 + 4 = 19 + (36 + 4)
= 19 + 40 = 59
Or to rearrange a little:
What is 2 × 16 × 5?
2 × 16 × 5 = (2 × 5) × 16
= 10 × 16 = 160
Distributive Law
The 'Distributive Law' is the BEST one of all, but needs careful attention.
This is what it lets us do:
3 lots of (2+4) is the same as 3 lots of 2 plus 3 lots of 4
So, the 3× can be 'distributed' across the 2+4, into 3×2 and 3×4
And we write it like this:
a × (b + c) = a × b + a × c
Try the calculations yourself:
- 3 × (2 + 4) = 3 × 6 = 18
- 3×2 + 3×4 = 6 + 12 = 18
Either way gets the same answer.
In English we can say:
We get the same answer when we:
- multiply a number by a group of numbers added together, or
- do each multiply separately then add them
Uses:
Sometimes it is easier to break up a difficult multiplication:
Typeface 2 6 4 X 8
Example: What is 6 × 204 ?
6 × 204 = 6×200 + 6×4
= 1,200 + 24
= 1,224
Or to combine:
Example: What is 16 × 6 + 16 × 4?
16 × 6 + 16 × 4 = 16 × (6+4)
= 16 × 10
= 160
We can use it in subtraction too:
Example: 26×3 - 24×3
We could use it for a long list of additions, too:
Typeface 2 6 4 X 4
Example: 6×7 + 2×7 + 3×7 + 5×7 + 4×7
6×7 + 2×7 + 3×7 + 5×7 + 4×7
= (6+2+3+5+4) × 7
= 20 × 7
= 140
And those are the Laws . . .
. . . but don't go too far!
The Commutative Law does not work for subtraction or division:
Example:
- 12 / 3 = 4, but
- 3 / 12 = ¼
Typeface 2 6 4 0
The Associative Law does not work for subtraction or division:
Example:
- (9 – 4) – 3 = 5 – 3 = 2, but
- 9 – (4 – 3) = 9 – 1 = 8
The Distributive Law does not work for division:
Example:
- 24 / (4 + 8) = 24 / 12 = 2, but
- 24 / 4 + 24 / 8 = 6 + 3 = 9
Summary
| Commutative Laws: | a + b = b + a a × b = b × a |
| Associative Laws: | (a + b) + c = a + (b + c) (a × b) × c = a × (b × c) |
| Distributive Law: | a × (b + c) = a × b + a × c |
