9 - 3 x 2 = 12
9 -3 x 2 = 3
Give the correct order of operations.
Parenthesis, Exponents (still correct if step not included), Multiplication/Division, Addition/Subtraction
3 + 4 x 0.5
7.5
(14 + 6) x (12 -4) -9
151
the sum of 9 and 3 divided by 3 equals...
( 9 + 3 ) ÷ 3 = 4
10÷5 x 2.2 = 4
10÷5 x 2.2 = 4.4
What is the acronym we use to remember the correct Order of Operations?
BEDMAS
2.9 + (18.5-12.2)
9.2
(15.5 - 5) x 10 + 3
108
12.43-2.437
9.993
5.75 x 5 +1 = 30
5.75 x 5 + 1= 29.75
If I have division and multiplication in my numerical expression, I should move from __________ ___ _________.
left to right
1.8 + 3.2 x 4.5 - 0.7
15.5
0.3 x 0.3 + 4 x 0.5
2.09
85.753 + 46.6
132.353
4 + 5 + 7 - 3.2 x 2 = 224
4 + 5 + 7 - 3 x 2 = 22.4
If I have addition and subtraction in my expression, I should move from ______ ___ _______.
left to right
( 4 x 4.5 ) - 0.06
17.94
2.9 + (185 / 5)
39.9
9.9 x 8.8
87.12
The problem was 19.5 - 5 x 2 + 3. My answer was 32. What did I do wrong?
I did not multiply first. The answer should be 12.5
Why is it important to know BEDMAS as a mathematician?
So that everyone is solving the problem in the same way
7.745 + 3 x (8 ÷ 4)
13.745
2.95 x ( 9 x 9 + 2) - 8
236.85
54.2 X 32
1,734.4
