The term 'microlith' is strictly to be applied only to tools made on microbladeor bladelets having a maximum length of 50 mm and a width of 12 mm or occasionally on small flakes, by blunting one or more margins by steep retouch. They are associated with the Mesolithic age. The technological hallmark of this period is tiny stone tools or 'microliths. Microliths were too small to be used as tools individually; instead, they were used as components of tools and weapons by being hafted in bone, wood or reed handles and shafts.
1360 ÷ 8 + 490 ÷ √49 + ? = 150 × 2
√(2670+ √(1141+ √(260- √(1251- √(637+ √1521) ) ) ) ) =?
√256 * 3 – 15% of 300 + ? = 150% of 160
20 * 8 + 40% of 100 + 60% of 150 = ?
14 × 6 + 9 × 11 = (82 – 3) × ?
(43)² - (28)² + (32)² = ?% of 2500
? = √2704 ÷ (25% of 104) + 73
