2) Reduce

6 over 8

The term "reduce" refers to the act of making something smaller or decreasing its size, quantity, or intensity. It can be used in various contexts, such as reducing the size of a file or reducing the amount of waste produced. In general, reducing something implies a decrease or a simplification of the original state, often with the goal of achieving efficiency or minimizing impact.

12

18

Not sure.

The correct answer is 12 because according to the order of operations, multiplication should be done before addition. So, 2 multiplied by 3 equals 6, and then adding 6 to the initial 6 gives a total of 12.

7) 2+18-6x5÷2

35

-5

20

5

Not sure.

The given expression involves addition, subtraction, multiplication, and division. Following the order of operations, we first perform the multiplication and division from left to right.

6 multiplied by 5 is 30, and then dividing it by 2 gives us 15.

Next, we perform the addition and subtraction from left to right.

2 plus 18 is 20, and then subtracting 15 gives us 5.

Therefore, the correct answer is 5.

9) Calculate 4-2(3-1)

0

4

6

2

Not sure.

The given expression is 4-2(3-1). To solve this, we first need to calculate the value inside the parentheses, which is (3-1) = 2. Then, we multiply 2 by 2, giving us 4. Finally, we subtract 4 from 4, resulting in 0. Therefore, the correct answer is 0.

10

-5

6

Not sure.

The given expression is 5-(-5)-7-(-3). To simplify this expression, we can first remove the double negative signs by changing -(-5) to +5 and -(-3) to +3. This gives us 5+5-7+3. Next, we can combine like terms by adding 5 and 5 to get 10, and subtracting 7 and adding 3 to get 6. Therefore, the correct answer is 6.
