Learning Task 2: Modified TRUE or FALSE, write True if the statement is correct, supply the correct answer if the statement is False.
Answer:
1) 10-4+9÷3 = 9 → True
2) (8+2)-(9-2²) = 6 → 5
3) 3²-15÷5+(6+4) = 16 → True
4) 5+2-3 = 4 → True
5) 5-5×4+1 = 1 → -14
6) 2 × 2 - 4 ÷ 2 + 4 = 12 → 6
7) (-3)²-12+2 = -1 → True
8) 3 × 8 + 16 ÷ 4 = 28 → True
9) 10 + 2 + 4 ÷ 4 (4-3) = 2 → 13
10) 11-3²+3 = 5 → True
CHECK FIRST:
#USING PEMDAS/CALCULATOR#
1) 10-4+9÷3 = 9
= 10-4+9÷3
= 10-4+3
= 6+3
= 9
2) (8+2)-(9-2²) = 6
= (8+2) - (9-2²)
= (10) - (9-4)
= (10) - (5)
= 5
3) 3²-15÷5+(6+4) = 16
= 3²-15÷5+(6+4)
= (9)-3+(10)
= (6)+10
= 16
4) 5+2-3 = 4
=5+2-3
=(7)-3
=4
5) 5-5×4+1 = 1
=5-5×4+1
=5-(20)+1
= (-15)+1
= -14
6) 2 × 2 - 4 ÷ 2 + 4 = 12
=2 × 2 - 4 ÷ 2 + 4
= (4) - 4 ÷ 2 + 4
= (4) - 2 + 4
= (2) + 4
= 6
7) (-3)²-12+2 = -1
= (-3)²-12+2
= (9)-12+2
= (9)-10
= -1
8) 3 × 8 + 16 ÷ 4 = 28
= 3 × 8 + 16 ÷ 4
= (24) + (4)
= 28
9) 10 + 2 + 4 ÷ 4 (4-3) = 2
= 10 + 2 + 4 ÷ 4 (4-3)
= 10 + 2 + 1 (1)
= 10 + 2 + 1
= 12 + 1
= 13
10) 11-3²+3 = 5
= 11-3²+3
= 11-(9)+3
= (2) + 3
= 5
"Keep in mind: If you mix up the order of parenthesis, exponents, multiplication and division, and addition and subtraction, the PEMDAS rule will help you against taking the wrong answer."
