EQUATION VALUE CALCULATION. OPERATIONS SEQUENCE AND PARENTHESES.
1. Find out the sequence of operations do
your sums.
| 100 - 24 + 30 - 7 = ..... (60 - 48) + 24 - 8 = ..... |
100 - (36 - 16) + 5 = ..... (30 + 10) - (50 - 20) = ..... |
(24 + 36) : 6 = ..... 24 + 36 : 6 = ..... |
2. Find out the
sequence of operations and write the operations in your copybook. Check if the answer is
among the numbers beside.
| 5 384 + 6 098 - 6 596 51 600 - (3 218 + 24 596) 312 000 - 96 153 - 8 513 (48 302 - 9 118) + 682 |
4 886, 10 896, 4 996 24 796, 23 786, 33 796 207 334, 216 334, 207 226 40 876, 40 866, 39 866 |
3. Calculate.
Find the right answer.
| 520 - 30 + 80 + 63 = 940 - 80 - 4 · 15 - 70 = 380 + 60 - 25 · 2 = 186 + 9 - 2 · 30 = |
|
150 + 70 - 100 : 2 = 460 - 4 · 20 + 66 = 720 - 60 : 2 + 98 = 260 + 30 · 3 + 72 = |
