I got 70% in mathematics ❤🎉 moving from 43 to 70 isn't a joke thank you Malome

[@zee_yot]

Wat was ur study method

[@lowkeydemodest8381]

Please tell us your study method dawg

[@DisLimit]

@@lowkeydemodest8381 Hey y'all.📑 1. UNDERSTAND THE BASICS: Make sure you have a strong foundation in fundamental concepts like fractions, decimal, geometry etc. 2. BREAK IT DOWN: Break down complex topics into smaller manageable chunks, focus on one concept at a time. 3. PRACTICE CONSISTENTLY: Regular practice helps build math muscle! Set aside a specific time each day to practice solving problems. 4. USE A VARIETY OF RESOURCES : -Textbooks -online resources (khan academy, math way but the one I recommend the most *Siyavula*) -video lectures -practice worksheets (past papers) -online forums(Reddit, stock exchange etc) 5. WORK ON THE PROBLEM-SOLVING STRATEGIES : -read the problem carefully -identify the type of problem (algebra, geometry etc) 6. SEEK HELP WHEN NEEDED: Don’t hesitate to ask teachers classmates, or online resources for help when you're stuck. 7. APPLY MATHS TO REAL LIFE SITUATIONS : Try to relate math concepts to everyday life. This helps make math more meaningful and interesting. 8. TAKE BREAKS: Math can be challenging, so take breaks to refresh your mind and come back to problems with a fresh perspective. 9. STAY ORGANIZED: Keep all your study materials, including notes and practice problems, organized and easily accessible. ❤I promise if you follow this... You will achieve and above all PRAY NEVER NEGLECT YOUR LORD JESUS CHRIST✝🥺

[@pholoshomasethe8038]

Mr Mlungisi sir, what happens when you get both a square root and a fraction and then they ask for the first principle ?

[@khanyamethusi8127]

Thank you sir for making this topic easy to understand

[@amahlemdabuli2690]

Thank you sir for introducing this topic early thank you very much.. And i'd like to ask a question by your second example why didn't you just multiple exponent ^3 and get (x^3+3xh+h^3-x^3) ** (^) by that I'm meaning exponent

[@MlungisiNkosi]

Oh yah that’s another option as well

On the 2nd example...after simplifying (x+h)^3- x^3...why did you change -x^3 -to x^2

[@MlungisiNkosi]

It must’ve been a mistake. Sincere apologies

Hello sir i have been part of the team since last year,this year i am doing my first year at Uni so i am interested in starting my own channel which i just did so i wanted to ask: 1.how do you edit the video in such a way that it shows what you are about to teach and your picture? 2.What are you using to end up writing on a screen full of markers like way you taught? 3.how do you insert your face at the bottom left corner when you're speaking? I know i am asking too much but i would also like my channel to grow please respond.
