Equivalent fractions: change part size while preserving value
We derive the fundamental fraction property from one length and simplify notation without changing the number.

Comparing fractions: put the numbers on one scale
We compare fractions through common parts, a number line, and benchmarks 0, 1/2, and 1, then check the order by estimation.
Society
Proportion and scale: which relationship must stay fixed?
We solve proportions through an invariant ratio, distinguish direct and inverse relationships, and check units.
Society
Percent: one hundredth instead of three formulas
We connect percent to fractions and decimals, calculate discounts and growth through a unit, and identify the base from which a percentage is taken.
Society
A fraction is a number, not two numbers stacked together
We connect part of a whole, measurement, division, and a point on a line so numerator and denominator gain precise meaning.
Society
Checkpoint: fractions, ratios, percentages, and transfer
Ten new problems test modeling, calculation, explanation, error correction, and transfer to a new setting.
Society
Entry diagnosis: find the first missing support
Ten short problems locate the right starting point without judging the learner or demanding perfect recall of school rules.
Society
Ratio: a recipe that survives every scale
We read `2:3` as a relationship between two quantities, build tables of equivalent ratios, and find a unit rate.
Society
How we will learn mathematics: from memorizing to understanding
The course follows a dependency map: every new step rests on an earlier idea, and understanding is checked through explanation and transfer to a new situation.

Operations with fractions: name the counting unit first
We add, subtract, multiply, and divide fractions through meanings of operations rather than four unrelated rules.

Free Cloud & DevOps course from zero: terminal to Kubernetes
Shanraq has opened a free Cloud & DevOps course for people with no infrastructure background. Across 24 lessons, learners work with the terminal, Linux, networks, Docker, CI/CD, a cloud server, HTTPS, Kubernetes, and recovery after failure through one running service.
IT
Networking without magic: IP, port, DNS, HTTP, and TLS
Trace a request from a domain name to a process socket and localize failures layer by layer.
IT
OpenTofu and Ansible: infrastructure and configuration as code
Validate a resource description, produce inventory, and apply idempotent host configuration.
IT
Build and publish one verified image
Publish to a registry only after tests and promote one digest across environments.
IT
Health checks, limits, and graceful shutdown
Distinguish liveness from readiness, set resource boundaries, and test shutdown behaviour.
IT
Terminal and Git: a reproducible working point
Navigate the workspace, review a change before committing, and return to a known version without deleting history.
IT
Before you begin: why Cloud & DevOps now
A detailed introduction to this free practical course: why infrastructure skills are growing with cloud, AI, and data centres, what Kazakhstan is building, and what you will learn without a promise of an instant career.
IT
Processes, signals, services, and logs
Observe a PID, graceful shutdown, and structured logs, then read a systemd unit as a startup contract.
IT
Ubuntu server: SSH keys, updates, and a firewall
Connect as an unprivileged user, close unnecessary ports, and verify access from a second session.
IT
A container: a bounded process, not a tiny VM
Run a first container, observe namespaces and an immutable image, and distinguish a process from a virtual machine.
IT
Domain, reverse proxy, and automatic HTTPS
Point DNS at the server, serve CloudLab through Caddy, and verify the TLS chain externally.
IT
Cloud: IaaS, cost, IAM, and shared responsibility
Design minimal virtual infrastructure, a budget, and access before creating a billable resource.
IT
Docker Compose: services, networking, and declarative startup
Start the application and reverse proxy from one declaration and reach a service by DNS name inside the network.
IT
Why Cloud & DevOps now: infrastructure, roles, and boundaries
Separate data-centre growth from job-title growth and map the skills of cloud engineering, DevOps, platform engineering, and SRE.
