Bodmas worksheet...
BODMAS 1. Brackets 2. Orders (i.e. Powers and Square Roots, etc.; exponents) 3. Division & Multiplication (left-to-right) 4. Addition & Subtraction (left-to-right)
Addition & Subtraction (AS) (left-to-right) •
1–2+3=
2
•
4+8–2+5=
•
10 + 14 – 22 = 2
•
32.5 – 1.5 + 16.8 = -14.2
•
1.26 + 5.31 – 4.15 = 2.42
15
Division & Multiplication (DM) (left-to-right) •
4 x 3 ÷3 = 4
•
2÷1x3=6
•
25 x 4 x 2 ÷5 = 38.4
•
12 ÷ 4 x 6 ÷ 2 = 4.5
•
1.2 x 5 x 6.5 ÷ 3 ÷ 10 = 1.3
Division, Multiplication, Addition & Subtraction (DMAS) •
5 – 6 + 4 x 7 = 29
•
10 ÷ 5 – 2 + 4 = -4
•
9 – 2 x 2 – 3 =2
•
12 ÷ 2 x 6 – 5 = 6
•
8 ÷ 4 – 8 + 5 x 9 = 39
Orders, Division, Multiplication, Addition & Subtraction (ODMAS) Before you do any parts of the sum involving Divisions, Multiplications, Additions or Subtractions (DMAS), perform the Orders first Orders = anything involving a power or a square root •
42 = 16
•
√ 36 = 6
•
√9 = 3
•
52 =25
Orders, Division, Multiplication, Addition & Subtraction (ODMAS) If an Order contains a sum within itself, simply it first according to the rules of DMAS •
√ 1+ 3+ 5 = 3
•
√ 70−10 + 4 = 7.48
•
√ 2 X 8 X 9 = 12
•
√ 64−10÷ 2−10 =7
•
√ 9 X 10÷2+4 =7
Orders, Division, Multiplication, Addition & Subtraction (ODMAS) •
2 × 32 - 8 = 10
•
√ 9 – 22 = -1
•
√ 1+3 X 5+7 = 11
•
82 ÷ 4 2 + 10 x 2 = 24
•
4x
√ 64−10÷ 2−10 + 3 = 27.1
Brackets, Orders, Division, Multiplication, Addition & Subtraction (BODMAS) In any given sum, start with anything inside Brackets. •
7 x (4 + 8) = 84
•
63 ÷ (17 – 8) = 7
•
8 + (7 – 6) x 4 = 12
•
(8 – 4) + (24 ÷ 2) = 16
•
(8 – 4) + (24 ÷ 2) x (27 – 17) = 124
Brackets, Orders, Division, Multiplication, Addition & Subtraction (BODMAS) “Sub-sums” contained within Brackets are worked out according to rules of ODMAS •
2 x (4 x 3 + 8) =40
•
30 – (20 – 8 ÷ 2) = 14
•
8 + (42 ÷ 6 – 3 x 2) x 4 = 12
•
(10 – 4 + 2 ÷ 2) - (26 – 24 ÷ 2) = -7
•
(8 ÷ 4) x (31 – 3 x 10) x (12 ÷ 2 - 5) = -2
Brackets, Orders, Division, Multiplication, Addition & Subtraction (BODMAS) •
7 + (6 × 52 + 3) = 160
•
√ 4+(19−7)
•
√ 1+ 3 x 5 – (4+ 2) – 3 =
– (3 + 2) = -1
√ 36 + 3) = ¿
•
36 ÷ 3 +
•
42 – (64 ÷ 8 - 5) 2 + 2 =
Dealing with positive and negative integers •
-10 + 3 = -7
•
4 + +4 = 8
•
-20 – -17 = -3
•
-6 + -3 = -9
•
-25 – (-15) =
•
5 + (-2) =...
