Mystery
9 - 3 x 2=12
Correct answer is 3. Do x then -, not - then x.
14 - 2 __ 7 = 0
14 - 2 x 7 = 0
Write the expression -
double the product of 3 and 4
2 x (3 x 4)
Why is it important to know Order of Operations (PEMDAS) as a mathematician?
So everyone can solve every problem the same (correct) way.
64 = 7 + 1 x 8
added first instead of multiplying first
Add the missing parenthesis to make it true
1 x 3 + 4 x 5 = 35
1 x (3 + 4) x 5 = 35
Find the sum seven and the of difference of ten and two
7 + (10-2)
Bonus what are the first 5 multiples of 7
7 , 14, 21, 28, 35....
4 x 3 - 2 x 5
12 - 2 x 5
10 x 5
50
4 x 3 - 2 x 5
12 - 10
2
5 x 3 - 4 x 1 - (8 + 2) =1
5 _ 14 ÷ 2 × 5 = 40
5 + 14 ÷ 2 × 5 = 40
four times the sum of three and fourty
4 x (3 +40)
70 + 7 x (9 - 3) x 11
What should you do first to solve? why?
What would you do next? Why
7 x 6 first mult/division from left to right
4 + 5 + 7 - 3 x 2 = 26
You need to follow PEMDAS and do x first. Correct answer is 10.
Add the parenthesis to make it true
6 x 1 + 5 - 3 = 8
6 x 1 + (5 - 3) = 8
The quotient of six and two, added to 5 minus 2
(6/2) + (5-2)
I had 2 boxes of a dozen donuts, I gave Mr. K half and then Ms. Keating took 1 of what was left.
Write an expression to match the equations
( 12 x 2 ) divided by 2 - 1
50 - 1 = 7 x 5 + 2
need to put a parenthesis around 5 +2
49 = 7 x (5+2)
(40 + 4) __ 11 + (2 - 1) = 5
(40 + 4) divided by 11 + (2 - 1) = 5
seven equal groups of the difference of nine and ten
(10 - 9 ) / 7
