A compound sentence is a sentence made up of two independent clauses joined by a coordinating conjunction (like and, but, or) or a semicolon. Each clause can stand alone as a complete sentence. Example: I wanted to go for a walk, but it started raining.

STEM education is a teaching approach that integrates science, technology, engineering, and mathematics into real-world, problem-solving learning. Students use inquiry, creativity, and hands-on projects to explore how things work rather than only memorizing facts. STEM helps build critical-thinking, teamwork, and future-ready skills needed in modern education and careers.

STEM education activities for elementary students are hands-on learning projects that integrate science, technology, engineering, and math to build problem-solving and critical-thinking skills. Examples include building paper bridges, coding with simple apps, measuring plants, and experimenting with magnets. These activities make learning practical, creative, and engaging for young learners

No single country has the best education system in the world, but Finland, Singapore, Japan, South Korea, and Canada are widely recognized among the strongest due to high academic standards, effective teaching, equitable access, and a focus on student well-being. What defines the “best” system ultimately depends on priorities such as access, innovation, and learning outcomes.

STEM education shapes the future by developing critical thinking, problem-solving, collaboration, and technology skills needed for tomorrow's workforce. It prepares students for careers in science, technology, engineering, and mathematics while improving learning outcomes, supporting innovation, and strengthening economic and social progress globally.

The United States typically ranks between 10th and 15th globally in education, depending on the ranking framework used. While the U.S. performs strongly in higher education and university quality, it ranks lower in K–12 outcomes, particularly in mathematics and science compared to countries such as Finland, South Korea, and Canada. Public education rankings generally place the U.S. lower than overall system rankings due to structural variation and inequality.

In math, factors are numbers that multiply together to give another number. A factor divides a number exactly, with no remainder. For example, 1, 2, and 4 are factors of 4 because each divides evenly into 4. Factors are used in multiplication, division, algebra expressions, and problem-solving across many areas of math.

Long division is a step-by-step method for dividing one number by another when the answer is not obvious. To do long division, follow this sequence:
✔ Divide The First Part of The Dividend by the Divisor
✔ Multiply The Divisor by The Result
✔ Subtract To Find the Remainder
✔ Bring Down the Next Digit, And
✔ Repeat Divide–Multiply–Subtract–Bring Down Until No Digits Are Left.

If there is a number left over, that’s the remainder. This method works for whole numbers, decimals, big numbers, and even polynomials

Mean, median, mode, and range are basic measures used in math to describe a set of numbers. The mean is the average, the median is the middle value, the mode is the most frequent value, and the range shows how spread out the numbers are. These measures help summarize and analyze data in a simple way.

Theoretical yield is the maximum amount of product that can form from given reactants, based on the balanced chemical equation. Percent yield measures reaction efficiency using the formula: Percent Yield = (Actual Yield ÷ Theoretical Yield) × 100.

Squared in math means multiplying a number by itself. It is written with the exponent 2, like 5², which equals 5 × 5 = 25. Squaring is used in geometry, formulas, and real-life measurements such as area. If a number has a superscript 2, it means the number is being squared.

The golden ratio in math is a special number—approximately φ ≈ 1.6180339887 — that appears when the ratio of two quantities equals the ratio of their sum to the larger quantity. This unique proportion creates naturally balanced and visually pleasing relationships between numbers.
