What does the "e" in bedmas stand for?
Exponents.
Because the order of operations states that the order in which you perform mathematical operations.
The order is B: brackets, E: Exponents, D: Divide, M: Multiply, A: Add, S: Subtract

Indicate whether these 3 situations would result in a positive or negative value:
a) spending 15$
b) diving down 25m
c) scoring 3 goals
a) negative
b) negative
c) positive
explanations:
a) because you would have 15$ less than what you started with therefor -15 (negative)
b) you are going deeper which means more below therefor you are -25m (negative)
c) you have 3 more goals than what you started off with which means +3 (positive)

Round 763 852 to the nearest 10 000th
760 000
because the 10 000th spot is 6 and since the 1000th spot is a 3 it isn't rounded up to a 7. It therefor remains a 6.

Calculate the following equation using the rules for order of operations.
18 - 2 x 9 + 15= ?
15.
Because -2 x 9= -18, 18-18=0, 0+15=15

Start at +8 and move -3.
What point would you end up at?
+5.
Because 8-3=5

List the smallest number we must add to 73 to make it a factor of 3.
2.
If you add 2 to 73 you would get 75. 3 goes into 75, 25 times therefor the smallest number you can add to 73 to make it a factor of 3 would be 2.

What is the answer to this equation?
(9+24) divided by (17 - 2 x 3)
33/11 or 3
(9+24= 33)
(17-6= 11)
=33/11 or 3

List all the factors of 18.
1, 2, 3, 6, 9 & 18.
Since all the possible ways of writing 18 in factored form are 1x 18, 2x 9 & 3x 6, all the factors are 1, 2, 3, 6, 9 & 18.
300
Is this pair of fraction equivalent or not equivalent?
4/3 and 16/9
Not equivalent.
Because for the denominater 3x3=9
But for the numerator 4x3 should have been 12 and not 16.

Find the total cost of purchasing a new car if the base price is $18758, air conditioning costs $1235, wheels cost $833 and taxes, transportation and other options cost $3342.
The total cost of the car is $24,168
Because:
$18 758
$1 235
$833
+$3 342
________
$24 168

Name a prime number that has only 2 factors, the number 1 and itself.
Answers can vary from 2, 3, 23, 47, 17 or 37, etc...
400
Is 1/3 less than or greater than 2/5?
1/3 is less than 2/5.
Because 1/3 x 5= 5/15
& 2/5 x 3 = 6/15
6/15>5/15
so, 2/5>1/3

What 3 numbers should come next in this sequence?
1, 4, 9, 16, 25, ...
35, 48 & 63
Why? Because:
4-1=3
9-4=5
16-9=7
25-16=9
therefore everytime you add 2 to what you previously went up by so to get the next numbers you would do:
25+11=35
35+13=48
48+15=63
500
What is the answer to this equation?
(-2)(+5)(-1)(+3)(-4)(-2)= ?
+240.
Because 2x5x1x3x4x2= 240 and since there is an even number of negative signs the answer will be positive.

Sherry jogged for 1/3 of an hour on Monday and 1/4 of an hour on Tuesday. Darcy jogged for half of Sherry's time on both days. What fraction of an hour did Darcy jog?
Darcy jogged 7/24 of an hour.
Because (1/3)(1/2)= 1/6
and (1/4)(1/2)= 1/8
1/6+ 1/8= 7/24
