states that theology should be practical and that we should be living out ‘church’. Praxis means that we should be seeking to do actions of faith within our daily lives and particular situations rather than seeking to create new expressions of church; these fresh expressions are popular in bringing people into the church but not necessarily productive in how they address the situations that people are in or prejudices faced. Examples of praxis models in use often consist of people standing up for their

algebra as placeholders for unknown numbers. If you see "3 + x"‚ don’t panic! All this means is that we are adding a number who’s value we don’t yet know. Term: A term is a number or a variable or the product of a number and a variable(s). An expression is two or more terms‚ with operations between all terms. Polynomial: Mathematical sentence with "many terms" (literal English translation of polynomial). Terms are separated by either a plus (+) or a minus (-) sign. There will always be one more

Our technology is developing by leaps and bounds‚ which constantly afford us tremendous assistance‚ but in terms of simplifying people lives‚ we should not neglect its adverse effects. Modern technology complicates our lives rather than simplifies them. The constant development of technology brings about/generates new and increasingly complicated knowledge‚ which we must understood or even mastered as it’s people’s survivable necessity. People truly have to learn more techniques than ever before

DeMorgan’s theorems state the same equivalence in "backward" form: that inverting the output of any gate results in the same function as the opposite type of gate (AND vs. OR) with inverted inputs De Morgan’s theorem is used to simplify a lot expression of complicated logic gates. For example‚ (A + (BC)’)’. The parentheses symbol is used in the example. _ The answer is A BC. Let’s apply the principles of DeMorgan’s theorems to the simplification of a gate circuit:

small group instruction‚ I used the expression “Okey Dokey” and to my astonishment‚ the four-grade students began to laugh and repeat “Okey Dokey” with amusement. I asked them why they were laughing and they responded that the expression “Okey Dokey” was old fashioned and it sounded very funny to them. I was very surprised‚ I did not think I was so old‚ but decided not to use it again. However‚ that was not the end of my language bloopers. One day I used the expression “It’s a pity” and my colleagues
