A Lógica Matemática utiliza conectivos para relacionar proposições. Um conectivo de extrema importância na lógica é o condicional que representamos por uma seta (!$ → !$). por !$ p !$ e !$ q !$. A linguagem "Se !$ p !$, então !$ q !$" pode ser representada por !$ p !$ !$ → !$ !$ q !$. A grafia til (!$ \sim !$) serve para negar uma proposição. Então a proposição lógica !$ \sim q → \sim p !$ é chamada de contrapositiva da forma lógica !$ p !$ !$ → !$ !$ q !$, da qual também é equivalente.

Boy in London died after being stabbed multiple times.
A 16-year-old boy died after he was stabbed a number of times in north-west London by a group who had chased him, police have said.
The Metropolitan police were called to Munster Square in Camden, close to Regent's Park, at about 11.10pm on Monday. The boy was pronunced dead at the scene, with paramedics in attendance, and his next of kin were informed.
DCI Paul Healy said in a statement that police were in the early stages of their murder investigation and appealed for members of the public to "do the rigth thing and speak to us", with no arrests yet made.
"We believe the victim was chased around the square by a number of suspects prior to being stabbed a number of times," he said. "The suspects made off in a vehicle which was discovered burnt out nearby. Another vehicle believed to be involved in the incident was also found burnt out some distance away."
At the scene on Tuesday afternoon next to Munster Square, which sits in the middle of a number of tall council blocks, a large police cordon remained in place and stretched across a number of nearby roads. Residents said the cordon was so large because the boy had been chased.
A resident, Rosanara Begum, told the Evening Standard: "The boy was running away from them, Then we saw the two boys holding him and the other one stabbing him"
"As soons as I heard: 'Help me, help me', I was on the phone to the ambulance. He was bleending a lot. The attackers were skinny and just looked like teenagers. They were running off and they were screaming and laughing."
Her daughter added: "We saw three boys all wearing hoods all covered in black, the middle one had a long black, marchete-type knife. It was really long".

Benefits of exercise
People are less active nowadays, partly because technology has made our lives easier. We drive cars or take public transport. Machines wash our clothes. We entertain ourselves in front of a TV or computer screen. Fewer people are doing manual work, and most of us have jobs that involve little physical effort. Work, household chores, shopping and other necessary activities are far less demanding than for previous generations.
We move around less and burn off less energy than people used to. Research suggests that many adults spend more than 7 hours a day sitting down, at work, on transport or in their leisure time. People aged over 65 spend 10 hours or more each day sitting or lying down, making them the most sedentary age group.
Inactivity is described by the Departament of Health as a "silent killer". Evidence is emerging that sedentary behaviour, such as sitting or lyiing down for long periods, is bad for your health.
Not only should you try to raise your activity levels, but you should also reduce the amount of time you and your family spend sitting down.
Common examples of sedentary behaviour include watching TV, using a computer, using the car for short journeys and sitting down to read, talk or listen to music. This type of behaviour is thought to increase your risk of developing many chronic diseases, such as heart disease, stroke and type 2 diabetes, as well as weight gain and obesity.
"Previous generations were active more naturally through work and manual labour, but today we have to find ways of integranting activity into our daily lives," says Dr Cavill.
Whether it's limiting the time babies spend strapped in their buggies, or encouraging adults to stand up and move frequently, people of all ages need to reduce their sedentary behaviour.
"This means that each of nus needs to think about increasing the types of activities that suit our lifestyle and can easily be included in our day," says Dr Cavill.
Crucially, you can hit your weekly activity target but still be at risk of ill health if you spend the rest of the time sitting or lying down.
