#Grammar                    #Lesson 2️⃣          TYPES OF TENSES 👉 There are mainly three types of Tenses 👆 Tense በዋናነት በሶስት ይከፈላል። ❶. Present tense ❷. Past tense ❸. Future tense ❶. Present tense 👉 Present tense is a grammatical term used for verbs that describe action happening right now. 👆 Present Tense የምንለው አሁን እየተፈጸመ ያለውን ድርጊት ለሚገልጹ ግሦች የሚያገለግል ሰዋሰዋዊ ቃል ነው። 👉 There are four types of Present tenses 👆 Present tense በአራት ክፍሎች እንከፍለዋለን። 1. Simple Present 2. Present Continuous 3. Present Perfect 4. Present perfect continuous ✅ Let's look at all four of them in one example 👆እስኪ አራቱንም በአንድ ምሳሌ እንመልከታቸው Simple present 👇          ➖ I work Present continuous👇          ➖ I am working Present perfect 👇       ➖ I have worked Present perfect continuous 👇       ➖ I have been working በዚህ ምሳሌ መሰረት ልዪነታቸው ምን ሊሆን እንደሚችል አስቡ እስኪ። ✅  አራቱንም በዝርዝር እንመልከታቸው 1. Simple Present tense 👉 The simple present, present simple or present indefinite is one of the verb forms associated with the present tensein modern English. It is commonly referred to as a tense, although it also encodes certain information about aspect in addition to present time. The simple present is the most commonly used verb form in English, accounting for more than half of verbs in spoken English. 👆 Simple present  በእንግሊዘኛ ከአሁኑ ጊዜ ጋር ከተያያዙት የግሥ ቅርጾች አንዱ ነው። Simple present በተለምዶ እንደ Tense ይቆጠራል፣ ምንም እንኳን ከአሁኑ ጊዜ በተጨማሪ ስለ ገጽታው የተወሰነ መረጃን ቢያስቀምጥም፧ Simple present የ tense ክፍል ነው እንጂ ራሱ Tense አይደለም።  Simple present  በእንግሊዝኛ በብዛት ጥቅም ላይ የሚውለው የግሥ ቅጽ ሲሆን በንግግር ጊዜ በእንግሊዝኛ ከሚነገሩ ግሦች ውስጥ ከግማሽ በላይ የሚሆነው ይይዛል። Formula of Simple present ✅  For positive ➡️ Subject + verb s/es + object E.g John loves to eat burgers. ✅ For Negative ➡️ Subject + do/does + not + verb + object E.g John doesn't love to eat burgers. ✅ For Question ➡️ Do/does + subject + verb + object +? E.g Does John love to eat burgers?      Function of Simple present 1. It's used to express habitual action or repeat action 👆 የተለመደ ድርጊትን ወይም የድግግሞሽ ድርጊትን ለመግለጽ E.g I get up at 5:00 am every day.      He goes to school every day.      We go to church every Sunday. N.B for repeat action we use adverb frequency like sometimes, usually..... 2. It's used to express universal truth or facts 👆 ሁልጊዜ እውነት ለሆነ ነገር/ አለም አቀፍ ተቀባይነት ላለው ነገር E.g Fish live in water.       The sun rises in the east. 3. It's used to express actual present 👆 አሁን እየተካሄደ ያለውን ነገር ለመግለጽ E.g Do you see those lights. 4. It's used to express a Future fixed action. 👆 የወደፊት ሁኖ ግን የተወሰነ ቀን ነው። E.g The train starts at 5:00 pm.       We go to the bank next week. To be continued..........

It stated that all matter was made up of small, indivisible particles known as ‘atoms’.All substances, according to Dalton’s atomic theory, are made up of atoms, which are indivisible and indestructible building units. Which are indivisible and indestructible building units. While an element’s atoms were all the same size and mass, various elements possessed atoms of varying sizes and masses. ምንም እንኳን የእነ Aristotle እና Democratus atomic theory ዎች ቢኖሩም በዋናነት ለ modern atomic theory መሠረት የሆነው የ Dalton atomic theory ነው ። ሀሳቡም በዋናነት የሚያጠነጥነው ከዚህ በታች የተጠቀሱት ነጥቦች ላይ ነው ። Postulates of Dalton’s Atomic Theory 🌷All matter is made up of tiny, indivisible particles called atoms. ሁሉም ቁስ አካል የተሰራው ትንሽ እና ደቂቅ ከሆኑ ወደምንም ነገር ከማይሰበሩ አቶም ከተባሉ ፓርቲክሎች ነው ። 🌷All atoms of a specific elements  are identical in mass, size, and other properties.

Mathematics             👑Chapter 1 👑 💋Relations and Functions 💋 ሰላም የተከበራችሁ ውድ የ entrance tricks ተማሪዎች Relations and Functions የሚለውን ሰፊ የሆነ ርዕስ ዛሬ ይዘንላችሁ መጥተናል:: መልካም ቆይታ 🥎 Definition and examples of relations 🚩A relation between two sets is a collection of ordered pairs containing one object from each set. If the object x is from the first set and the object y is from the second set, then the objects are said to be related if the ordered pair (x,y) is in the relation. Relation ማለት  ስብስቦች በስርዓት የሚዛመዱበት መንገድ ነው። ምሳሌ Suppose there are two sets X = {4, 36, 49, 50} and Y = {1, -2, -6, -7, 7, 6, 2}. A relation that states that "(x, y) is in the relation R if x is a square of y" can be represented using ordered pairs as R = {(4, -2), (4, 2), (36, -6), (36, 6), (49, -7), (49, 7) 🥎 Definition and examples of functions People also ask What is the formal definition of a function? A function is a relation that uniquely associates members of one set with members of another set. Function ማለት የ relation አይነት ሲሆን የ x value መደገም የለበትም። ምሳሌ (2,4),(3,4),(5,6) is functions (4,2),(3,5),(4,7) is not functions because 4 is repeated. 🥎Classification of functions (one to one, onto, even and odd) and inverse of functions 🚩An injective function (injection) or one-to-one function is a function that maps distinct elements of its domain to distinct elements of its codomain. Formally, it is stated as, if f(x) = f(y) implies x=y, then f is one-to-one mapped, or f is 1-1. አንድ መርፌ 💉 ለአንድ ሰው 🧙‍♂️። አንድ X ለአንድ Y. 🚩Onto function /serjection/is a function f that maps an element x to every element y. That means, for every y, there is an x such that f(x) = y. Y ያለ X መቀመጥ የለበትም ። 🚩if f(x) produces y, then putting y into the inverse of f produces the output x. x . A function f that has an inverse is called invertible and the inverse is denoted by f−1. 🚩A function f is even if the following equation holds for all x and −x in the domain of f : f(x)=f(−x) Geometrically, the graph of an even function is symmetric with respect to the y -axis, meaning that its graph remains unchanged after reflection about the y -axis. 🚩A function f is odd if the following equation holds for all x and −x in the domain of f : −f(x)=f(−x) Geometrically, the graph of an odd function has rotational symmetry with respect to the origin, meaning that its graph remains unchanged after a rotation of 180∘ about the origin. 🥎Operations on functions and composition of functions 🚩Sum(f + g)(x) = f(x) + g(x) 🚩Difference(f - g)(x) = f(x) - g(x) 🚩Product(f * g)(x) = f(x) * g(x) 🚩Quotient(f / g)(x) = f(x) / g(x) 🚩In the composition of (f o g) (x) the domain of function f becomes g(x). The domain is a set of all values which go into the function. Example: If f(x) = 3x+1 and g(x) = 2x , then f of g of x, f(g(x)) = f(x2) = 3(2x)+1.
