Solve: 3 + 4 - 2 x 3 using BEDMAS
3 + 4 - 2 X 3
= 3 + 4 - 6
= 7 - 6
= 1

State the rules for dividing fractions
Keep Change Flip
Natural Number : 1,2,3 ..
Whole Number: 0,1,2,3 ...
Integers: ...-2,-1,0,1,2, ...
Rational Numbers: any fractional numbers including, natural, whole, integers
Solve: 6 x 4 - 1 + (10 ÷ 5) + 2 ^ 2 in 30 seconds
6 x 4 - 1 + (10 ÷ 5) + 2 ^ 2
= 6 x 4 - 1 + 2 + 2 ^ 2
= 6 x 4 - 1 + 2 + 4
= 24 - 1 + 2 + 4
= 23 + 2 + 4 = 29
Half the point with a group of your choice!
250 for you, 250 for them!
Draw on the number line correctly: -2 ≤ x < 4 , x ∈ I
x = -2, -1 , 0, 1, 2, 3
Calculate the sum using LCM
13 / 20 + 13 / 50
LCM = 100
13 / 20 (5) = 65 / 100
13 / 50 (2) = 26 / 100
= 65/100 + 26 / 100
= 81 /100
