Magento 2 - Calling functions from a block from controller

Say I want to call a function from a Block while inside my Controller class which outputs on screen, how would i go about this?

Code for New/Module/Controller/Hello/World.php :

<?php
namespace New/Module/Controller/Hello/;
class World extends MagentoFrameworkAppActionAction


public function execute()

echo '<p>"Hello World"</p>';
var_dump(__METHOD__);

divide(10,1); <-- trying to do this




Code for New/Module/Block/Calculator.php

<?php
namespace NewModuleBlock;
class Calculator
public function divide($number1, $number2)

return $number1/$number2;

public function multiply($number1,$number2)
return $number1*$number2;

public function add($number1,$number2)
return $number1+$number2;

public function sub($number1,$number2)
return $number1-$number2;




I'm attempting to create a calculator and I'm not even sure this is the best way to go about calling functions to output on screen.

Any help would be much appreciated :)

You can call block methods by creating instance of that class.

<?php
namespace New/Module/Controller/Hello/;
class World extends MagentoFrameworkAppActionAction



/**
* Calculator
*
* @var NewModuleBlockCalculator
*/
public $calculator;

public function __construct(
MagentoFrameworkAppActionContext $context,
NewModuleBlockCalculator $calculator
)
$this->calculator = $calculator;
return parent::__construct($context);


public function execute()

echo '<p>"Hello World"</p>';
var_dump(__METHOD__);

//divides(10,1); <-- trying to do this

$this->calculator->divide(10,1);




Use Below code for it

<?php
namespace New/Module/Controller/Hello/;
class World extends MagentoFrameworkAppActionAction

protected $_calculator;

public function __construct(
MagentoFrameworkAppActionContext $context,
NewModuleBlockCalculator $calculator
)
$this->_calculator=$calculator;
parent::__construct($context);

public function execute()

echo '<p>"Hello World"</p>';
var_dump(__METHOD__);

$this->_calculator->divide(10,1); <-- trying to do this
