Answer:
hope this helped i was kinda confused by the question
Step-by-step explanation:
3 x 11 = 33
4 x 5 = 20
33 + 20 = 53
10 x 4 = 40
80 - 40 = 40
53 > 40
60 - 50 = 10
3 x 10 = 30
5 x 15 = 75
50 = 20 = 70
11 + 33 = 44
35 x 15 = 525
42 + 35 = 77
9 x 8 = 72
Step-by-step explanation:
Here we have to find sum of -1000 and 1000.
The two numbers are equal and opposite in sign.
While adding a positive and a negative , we have to subtract.
so subtracting 1000 -1000, the answer is 0.
Another concept is when we add a number and its negative, we use this property,
a + (-a) =0
For example 2+(-2) = 2-2 =0
Similarly 1000 + (-1000) = 1000-1000 =0
This explains the concept .

Answer: 12</h3>
Explanation:
Multiply 0.66666667 with 18 to get
0.66666667*18 = 12.00000006
The 6 at the very end is due to rounding error. In reality the 6's in 0.66666667 should go on forever. That 7 is from rounding up.
Anyways, the result 12.00000006 should be 12 exactly.
Note how
12/18 = 0.66666667
when using a calculator.
