MIXED OPERATIONS INVOLVING WHOLE NUMBERS

900 000 - 800 000 + 1 700 000 =

Answer explanation

900 000 - 800 000 + 1 700 000 =

For expressions with only addition and subtraction (or only multiplication and division), you perform the operations from left to right.

In this expression, you perform the subtraction first, followed by the addition, because both operations are at the same level of precedence.

900 000 - 800 000 = 100 000

100 000 + 1 700 000 = 1 800 000

2 500 000 + 500 000 - 1 300 000 =

Answer explanation

2 500 000 + 500 000 - 1 300 000 =

In this expression, both addition and subtraction are at the same level of precedence, so you perform these operations from left to right.

2 500 000 + 500 000 = 3 000 000

3 000 000 − 1 300 000 = 1 700 000

14 x (400 000 + 300 000) =

Answer explanation

14 x (400 000 + 300 000) =

In this expression, you first handle the operation inside the parentheses before performing the multiplication.

400 000 + 300 000 = 700 000

14 × 700 000 = 9 800 000

An electronics factory produces 2 860 000 units of light-emitting diode (LED).
All the units are packed equally into 80 boxes.
The electronics factory delivers 2 boxes to Azlan Electric Shop.
How many units of LED are received by the shop?

Answer explanation

To determine how many units of LED are received by Azlan Electric Shop, follow these steps:

1. Calculate the number of units per box:

   2 860 000 units / 80 boxes = 35 750 units per box

3. Calculate the total number of units delivered to Azlan Electric Shop:

   2 boxes x 35 750 units per box = 71 500 

So, Azlan Electric Shop receives 71 500 units of LED.

A company delivered 30 000 seats to a new stadium.

Then, it sent another 30 containers of seats to the stadium.

Each container carried 580 seats.

What is the total number of seats delivered to the new stadium?

Answer explanation

To find the total number of seats delivered to the new stadium, follow these steps:

2. Calculate the number of seats in the 30 containers:

   30 containers x 580 seats per container = 17 400 seats

4. Add the initial number of seats delivered:

   30 000 seats + 17 400 seats = 47 400 seats

So, the total number of seats delivered to the new stadium is 47 400.
