# Mathematics

We offer practice word problems from elementary and high school mathematics. In the 12 years of the portal's existence, we have collected and solved more than 18,000 word problems. If you find an error in our solution, please report it to us. We are happy to fix it and learn new things.Most of the problems were sent us by the students to improve math reasoning. We try to develop logical and critical thinking in children and youth. We collect examples from pupils who cannot calculate them or just want to confirm the correctness of their procedure and result.

**We consider mathematics a carrier of common sense**, without which succeeding in a further career or business is more challenging. We develop creative, critical thinking. Everything can be proven in mathematics, derived from basic knowledge (axioms). For example, each solution to the example can be verified by a correctness test. We will help you with our portal with math questions and problems with their solutions. If you are looking for math material, getting ready for a prize, a graduate, a monitor, or a nationwide knowledge test is also right here. In addition to examples, we also offer online math calculators.

06.07.2024 The summer holidays are in full progress.We solve interesting examples from mathematics that you send us. We are looking forward to the first of September!22.06.2024 The end of the school year is inexorably approaching. Pupils are sanding their desks, grades are closed, school trips are taking place and math is practically not taught in this heat.

20.05.2024 High school graduation exams have started. We wish the graduates a lot of strength in the maturity exam.

- The HCF

The HCF of two numbers is 18 and their product is 12960. Their LCM will be - The co-ordinates

The co-ordinates of the point P dividing the line segment joining the points A (1,3) and B (4,6) internally in the ratio 2:1 are - Billy 2

Billy has 3/4 of the money Derek has, and Derek has 7/9 of the Jason has. If they have a total of $680. How much does each person has? - Missing side length

Use the Pythagorean Theorem (a² + b²=c²) to find a missing side length: a = 5; c = 13 ; b=?

- Multiple and remainder

What is the least multiple of 7 which when divided by each one of 6,9,15,18 gives remainder 4 in each case? - A boat 2

A boat can travel with a speed of 13 km/h in still water.If the speed speed of stream is 4 km/h, then find the time taken 1) to go 68 km downstream . 2) to go 63 km upstream . - A passenger

A passenger train, 150 m long, passes a railway platform, 200 m long, in 35 seconds. Find: 7 1) speed of the train in km/h 2) the time taken by the train to pass a man cycling in the direction of the train at the rate of 9 km/h .
