The Corbettmaths Practice Questions on Function Machines (Number Machines)
Example 1: solving a one-step-equation using a function machine Example 2: ... Function machines are used to apply operations in a given order to a value known as the input. The final value produced is known as the output. A function machine can be applied to numbers or be used for algebraic manipulation. They can be used to solve number ...
Function Machine. A teaching resource for interactive whiteboards.The single step function machine adds or subtracts numbers to 10 or you can set your own function. There is also a more difficult 2 step function machine for more challenging examples.
This is a video from our nugget on function machines from our Primary Maths course. All our videos, questions and slideshows are made by subject specialist e...
The aim is that they see how both are essentially the same process. There are a large number of examples allowing for white board work. Pupils are then given a worksheet where they find the outputs for given function machines and inputs. The extension asks students to find inputs for given outputs with a hint at inverse function machines.
Function Machines. A Function Machine is a diagram that represents a machine that takes an input, applies a rule such as a set of operations and delivers the answer as an output. Your task is either to determine the input, the output or whatever operations take place inside the machine. Let's look at an example.

Function Machines. A function machine takes an input, applies a series of mathematical operations to it, and then outputs a result. Function machines are quite a common question type, especially in foundation maths papers. There are 3 main types of questions you could be asked.. Make sure you are happy with the following topics before continuing. Types of Numbers
This KS3 Function Machines worksheet puzzle gives students practise with using function machines to perform operations and inverse operations. How to complete this activity: Calculate the missing values to complete the single-operation and double-operation function machines. Locate the answers on the grid. Draw the shape in the relevant square. Shade in as appropriate. All of the answers are ...
An example of a function machine is shown below: Input of 2 Let’s now find what the output is if the input is 2. We find out what the output is when the input is 2 by placing 2 into the function machine. The first operation in the function machine is “multiply by 3”, so we multiply 2 (our input) by 3.
This will make sense after we have looked at an example. We have the function machine below. For a certain input, the output of the function is the same as the input of the function. Find the value of this input. The first step in answering this question is to create an equation for the output in terms of the input.
A function machine shows the relationship between two variables, the input and the output. Here is a function machine: Input → × 3 → + 2 → Output In this function we multiply the input by 3, then we add 2 to give us the output. If we put 5 into the function machine: 5 × 3 = 15 15 + 2 = 17 The output is 17
A number machine is a way of writing rules using a flow diagram. The equation \(3j - 6 = 9\) can be shown on a number machine by writing out the functions that have been applied to \(j\) in the ...

This can be demonstrated using a function machine. The function, multiply by 3 and then subtract 1 , can be applied to different values. If 5 is the input, the output is 14 because 5 × 3 – 1 = 14.
Function machines are logical ways to express a function. The number going into a function machine is called the input and the number coming out at the end is called the output. What is done to the input is called the operation. For example, in the function machine above is the input, is the operation and is the output. If the input is , the ...
In this example the height of the bars is randomly selected at line 170. Lines 180 to 270 then draw a "solid" bar and the edges are marked in black by lines 290 to 330. Lines 340 and 350 print out one letter representing the month of the year at the bottom of each bar. Notice that lines 60 and 70 set up two of the function keys.
